Hello,

I have a 120-gallon tank running two Rena xp3 filters with fish in the tank. I have both gravel and ornaments in the tank. I have both biostars and bioballs media. Unfortunately prior to adding fish I had no previous knowledge of the "cycling process" and purchased quite a few fish for my community tank. In all I have about 50/60 fish (over 60% small community fish like zebra danios, platies, mollies) with a few larger ones (4 Angels/2 gourammies /2 tin foil barbs and one rescue Pacu (which will be moving to a larger tank just for him). All fish are well and healthy however the challenge becomes keeping them that way during the cycling.

Tank has been up and gong for about two weeks. I’m testing twice a day while doing water changes (2x) of 20%-40%. Current testing results (API freshwater test) are:

Temp kept at 78-80 degrees
PH 7.0
Ammonia seen a low of .5 to a high of 2
N02 .5
No3 between 5 and 10

Yesterday was my first time using Prime (was using Amquel but it was lowering PH too much) and today began using Stability in hopes to get the cycling process along quicker. I am experiencing a bacteria bloom, as the water is cloudy every 8-12 hours, when noticed I test and change water accordingly. Feedings are 2x a day, little waste of food.

My questions are as follows:

By changing out the water am I prolonging the cycling and if so what’s are my options here?

Should I let the Stability run its course (since the prime is protecting the fish-considering the readings are detoxified)?

When levels are high I use a 3x dose of prime, is this correct?

All fish are swimming well however i have had a 3 losses (platies-which i believe to the rapid ph change) however I have noticed that some are swimming toward the top though not much labored breathing (plenty of water movement with the filters and aeration) would this be ammonia poisoning even though I am using the prime?

And finally what am i doing wrong and should be doing...other than removing fish as that’s simply not an option?

You should continue the 7-day cycling process that Stability instructs you with. Also, only make water changes after 24 hours of adding stability (wait 24 hours after each dose, before making any water change), because the free-floating bacteria will need time to settle on an object/gravel/filter media.

You should test for ammonia and add Prime accordingly, too.

When I first had an aquarium, it took me at least 3 months for ammonia-eating/nitrite-eating bacteria to settle in my bio-filter. The downfall of not using a product like Stability and waiting so long resulted in more than 20 fish deaths (luckily, I bought very cheap fish - 10 for a $1).

Labtest 57,

Thank you for the advice... i have been following it and will keep you posted...

Thanks for the post! By changing the water you are not necessarily prolonging the cycling process as long as you are adding Stability whenever you do a water change. The bacterial bloom could be a result of not having enough surface area for the bacteria to proliferate. Bioballs and Biostars only have external surface area for bacteria to grow. I would recommend using our Matrix along with the Stability as they go hand in hand with one another. Matrix provides both external and internal macroporous surface area that is ideal for the support of both nitrifying and denitrifying bacteria. Stability is good not only during the cycling process, but also as general aquarium maintenance such as after water changes, whenever adding new fish, or when medicating. When your nitrite levels are high you can definitely add 3x the instructed amount of Prime, however, we do not recommend continuously doing so. If you have added Prime, rest assured that your ammonia/nitrite/nitrates have been bound and are now detoxified. I would recommend continuing to add Stability daily and with water changes and maybe getting some Matrix to support both nitrifying and denitrifying bacteria that Stability is adding to your aquarium.
