A Solution for Ammonia in Tap Water

I moved to a new city recently, and where I lived before I never had any issues with ammonia in my tap water.  However, where I live now does have about 0.5 - 1 ppm ammonia in the tap water. Ammonia is very toxic to fish, and even more toxic at a higher pH.  My pH is rather high at 8.0, so I have a bit of a problem on my hands!
Thankfully, it's not the end of the world because there is a fairly simple solution.  I have always used Seachem Prime as my tap water dechlorinator, but in addition to removing chlorine and chloramines, Prime also has some other beneficial qualities.  It is capable of detoxifying ammonia, nitrite, and nitrate for up to 24 hours.  At the regular dosage, Prime efficiently detoxifies 1 ppm of ammonia, and in an emergency, it can be safely used up to 5 times its normal dose.  When the ammonia is detoxified, it remains in the aquarium in a non-toxic form, so the biological filter can still convert the ammonia to nitrites and then nitrates.

So there's my solution!  I already used Prime anyway to remove the chlorine from my tap water, and now I can keep using the dosage I've always used to additionally detoxify the 0.5 - 1 ppm of ammonia in my tap water.  Of course, Prime's detoxifying properties will wear off after 24 hours, but within that 24 hours, the biological filter will have converted it to nitrites and then nitrates anyway.  I have tested the tank water for ammonia the day after doing a large (90%) water change, and sure enough, the ammonia is down to zero.

Cheers to simple solutions!  :)

Food-related Color Change

I figured that with the high algae content in the Repashy Soilent Green food, Clover might become a little more yellow.  And he did!  I prefer him to be a nice clean, brilliant white color, but I don't dislike the yellow enough to stop using this gel food.  Here's the before and after, so you can see for yourself the difference!

Custom Goldfish Necklace

This necklace was custom-made from a photo of my goldfish, Chiba.  I had Chiba for a little over one year before he became ill with untreatable dropsy and died.  He was a very special fish and an absolutely perfect example (in my opinion) of the butterfly telescope.  It's nice to have something to remember him by.  You may recognize him from my avatar/logo!




















 

The seller has a few other goldfish necklaces listed for sale on her shop, and I'm sure she would welcome more custom orders if you want one of your own fish!

A Guide to Quarantine Procedures

A good quarantine procedure has three equally-important components:
-the quarantine tank setup,
-maintenance of the tank,
-and medications.
All three components work together for a successful quarantine experience. 

The Quarantine Tank
The Tank
The quarantine (QT) tank should provide at least 10 gallons of space per fish.  Sufficient space is always important for goldfish, but it becomes especially important in quarantine.  Quarantine should be a time for new fish to de-stress and get used to their new surroundings, but they can't de-stress if they're crowded.   Accumulated toxins from waste will increase their stress, and that's why providing at least 10 gallons of space per fish is so important. 

The tank does not have to be a traditional glass aquarium, but it should be a container with clear sides to provide a good view of the fish.  It will be important to notice any signs of disease, and that's difficult to do without a clear side view of the fish.  Sterilite brand storage bins are always food-safe, and thus are a good option for a QT container.  Not all brands of plastic bins are food-safe (and thus, safe for fish) so do your research before buying a container.  For larger plastic tubs, it's a good idea to use some sort of brace in the middle to keep them from bowing out too much when filled with water.  You can easily make your own brace out of plywood (see photo below). 

The Filter
The next consideration is filtration for the QT tank.  It's very important to have at least 10x filtration for sufficient water flow through the filter media.  This means that for a 10 gallon tank, you'll need a filter with a flow rate of at least 100 gallons/hour.  I prefer to use Aquaclear filters for quarantine tanks because they provide a lot of space for filter media, and they're highly customizable.  You can essentially use whatever type of filter media you want in them.  The filter should have a thin bottom layer of sponge (cut the large Aquaclear sponges in half lengthwise).  On top of the sponge layer, the filter should be filled to the top with biological media (ceramic beads and rings, bioballs, etc.).  All of this biological media should be taken from a healthy and well-established (cycled) tank of yours.  Ideally you should add the cycled media to the QT filter immediately before adding your new fish to the QT tank.  This way the beneficial bacteria living on the filter media won't starve by being placed into a tank with no fish for a few days while you wait for your new fish to arrive.

If you find that the filter output is too strong for your fish, you can cut a long strip of filter floss (a cheaper option is 100% polyester quilt batting) and secure it to the sides of the filter using small clamps (see photo below).  This allows you to maintain a high flow rate with your filter while keeping the strong current from pushing your fish all over the tank.  For very small or weak fish, it can also be a good idea to cut out a small cube of sponge, cut a hole in the top of it, and place it over the filter intake.  This will keep small and/or weak fish from getting stuck onto the filter intake.

Other Components
Lastly, an air stone is always a good addition to a quarantine tank.  It's important for the water to be well-oxygenated to decrease stress on the fish.  Don't forget a thermometer too! 

The video below shows my QT tank as an example.  It's a 27 gallon Sterilite storage bin with an Aquaclear 110 filter, an air stone, a glass thermometer, and a brace (made from a wood clamp) across the middle.


Maintenance
Diligent tank maintenance is always important for goldfish, but especially so during quarantine.  Once again, proper tank maintenance will help the new fish de-stress in its new environment rather than adding to its stress.  Even though the filter is full of biological media that should be full of beneficial bacteria, you will still need to test the water daily for at least the first week of quarantine.  You'll be testing for ammonia, nitrite, nitrate, pH, and checking the temperature.  The best test kit to use is the Freshwater Master Test Kit by API; it contains all the tests you'll need at a reasonable price.  Ammonia and nitrite should always be zero, while nitrate should be less than 10.  The pH should be stable, and somewhere between 7.2 and 8.4 (goldfish tolerate a wide range of pH, as long as it remains stable).  If at any time ammonia or nitrites register, a water change should be done immediately.  Your test kit and Python water changer will become your best friends during the quarantine process!

It's a great idea to do a near 100% water change for the QT tank every day for the first week or so.  Keep in mind that the fish is stressed and very susceptible to disease at this time, and fresh clean water is the best prevention against many goldfish diseases.  After the first week, water changes can be gradually scaled back as long as the water parameters remain at acceptable levels.  I recommend using Seachem Prime to remove chlorine and chloramines.  Prime is very concentrated, so you don't have to use a lot of it, and it's great because it also provides temporary protection in case of a sudden ammonia or nitrite spike.  It detoxifies ammonia and nitrite (up to a certain ppm) for up to 24 hours.   











Medications  
Salt
Hopefully you had the benefit of seeing your fish (photos, video, or in person) before it arrived so you could be sure to pick a fish that seems healthy.  But it's important to remember that even if a fish seems healthy at first glance, it could have issues that may eventually be transferred to your main tank.  And that's why quarantine is so important!  Typically, it should be assumed that all new goldfish have some type of parasites, and they should be treated accordingly.  The most typical medication used on new goldfish arrivals is salt.  That's right, just plain old NaCl!  It must be pure salt with no additives though, so your average table salt won't cut it.  I typically use and recommend API Aquarium Salt, which can be found at most pet or fish stores.  The purpose of the salt treatment is to kill an assortment of external parasites, and to do this the salt concentration must be brought up to .3%.  .3% is 3 level teaspoons per 1 gallon of water.  It's best to bring the salt concentration up slowly to avoid shocking the fish.  First add 1 teaspoon per gallon.  12 hours later, add another 1 teaspoon per gallon.  Then after another 12 hours, add another 1 teaspoon per gallon of water, and the salt concentration will be at .3%.  The salt should always be dissolved in a bucket of tank water before adding it to the QT tank.  Never add salt to the tank without dissolving it fully first.  Keep in mind that with each water change, you'll need to add back the amount of salt you took out.  For example; if you change 90% of the water, you will need to add back in 90% of the salt that was in the tank before the water change.  A salt concentration of .3% should be maintained for about three weeks to be sure any possible parasites are killed off.  During this time salt creep is a very real danger, so if in doubt, err on the side of caution.  As time goes on, it's a good idea to use a little bit less than 1 teaspoon of salt each time you measure, in an effort to offset salt creep.
* You can also use Morton Canning and Pickling salt.  This is much cheaper than using API aquarium salt, and it is just as effective and pure.  Keep in mind that because the grain size of Morton salt is so much smaller, .1% is 3/4 teaspoon per gallon (instead of 1 teaspoon per gallon).

Praziquantel
Prazi is the other medication typically used in quarantine, and this treatment kills gill and skin flukes.  Flukes are so common in goldfish that all new fish should be treated as if they have flukes.  Prazi is a relatively "safe" medication to use as it's difficult to overdose.  The most common type of prazi used by goldfish keepers is a liquid form, called PraziPro.  It's not as common to find this in local stores and you may need to order it online, so plan ahead!  The prazi treatment must be done in several repeated doses, because it only kills adult flukes, and does not touch fluke eggs.  The fluke eggs will not hatch with prazi present in the water, so each dose must have a couple days in-between with no prazi in the water to allow the fluke eggs to hatch so they can be killed.  I prefer to keep prazi in the water for 3 days, followed by 2 days with no prazi, and repeat this cycle 4 to 5 times.  In a QT tank, you'll be changing the water daily, so the prazi should be added after each water change for three days.  For two days after that, do the water changes like normal, but do not add prazi.  Then repeat this cycle through 4 or 5 more treatments.  The prazi treatment can be done at the same time as the salt treatment.  

Here's my video explaining how to dose the Aqua-Prazi:   


Observation
Some people choose to wait a few days before beginning any salt or prazi treatments.  I actually think this is a really good idea, because it gives the fish a chance to settle in and de-stress, and it gives you a chance to observe the fish's behavior before starting treatment.  If you're in no rush to get the fish out of QT quickly, then waiting up to 1 week before beginning any treatments may be a good idea.  Regardless of when you decide to begin treatments, be sure to carefully observe your new fish for the duration of their quarantine so you can detect potential problems early on.



















And last, but not least, enjoy your new fish!  If you follow the steps for proper quarantine, it's very likely that you will have a happy and healthy new fish that won't introduce diseases into your main tank!

Product Review | Repashy Soilent Green for Goldfish

I recently bought a new type of food to try with my goldfish, called Soilent Green, by Allen Repashy.  It's a premade gel food mix that you just add water to.  It's formulated for fish that eat algae and small living organisms, which is basically what the goldfish diet consists of, so I thought I'd give it a try.  Here are my thoughts about it, in an easy-to-read list format... 

Pros:
-The finished gel is very soft and easy for the fish to rip apart.
-Although the gel is very soft, it does not disintigrate in the water.
-It's very easy to make; just add water!
-A commercially-formulated food is more likely to have all the necessary vitamins and minerals in the correct proportions.
-It stays fresh in the refrigerator for up to two weeks.
-My fish find it very tasty!

Cons:
-It is expensive.
-Because it contains so much algae, it can cause a yellow tinge in predominantly white goldfish.

Overall, I really like the Soilent Green gel food, and I'll definitely keep using it!  In the past, I have mainly used Saki-Hikari sinking goldfish pellets.  I don't have any issues with that food, but I still would prefer to feed my fish a gel food, because I think the gel is easier for them to digest.  I have also tried making my own homemade gel food for my fish in the past, but I always felt it was not adequate for a few reasons.  For one thing, I think it's very difficult to get the right proportions of vitamins and minerals for optimal fish health in a homemade gel food.  I also thought the binding agent (unflavored gelatin) used in most homemade gel foods was not a very good choice for fish.  And lastly, it seemed to spoil quickly, even though it was stored in the refrigerator.  All in all, I feel there are just too many unknowns with homemade gel food, and I won't feed it to my fish in the future.  Now that I have such an easy alternative with the Repashy Soilent Green, I won't need to anyways! 

Here's a video showing how easy it is to make Soilent Green:
