Seachem Stability Fish Tank Stabilizer - For Freshwater and Marine Aquariums 100ml

This is probably the only product of seachems Im not a fan of. It works dont get me wrong but Ive used other products with better and faster results.

No significant changes in water quality. May be I expected too much from the product. My tank didnt clear up much, but it didnt kill any of my fishes, like other people said. I still have water test to run but no significant visual changes. I would think this is still good for small tanks to start up the tank, but I do not recommend it for exisiting tanks.

I dont know honestly, if it comforts you- buy it

I used this to cycle 4 tanks. It helped me cycle my first tank in a little less than 3 weeks, with fish in (Ill never do that again). But I will use this again, I still have a bottle on hand for my quarantine tanks.

This cycled my tank in two weeks. You do need to use Seachem Prime to do a 2 week fish in cycle. The trick is to neutralize the ammonia and nitrites with the Prime, rather than remove them through water changes. This keeps the ammonia and nitrite available to feed the bacteria you are growing. The neutralized Ammonia and Nitrites will still show up in your water tests, and will still be available to the bacteria, but will not harm your fish. I kept a close eye on my levels (and my betta, Gerard). I did water tests twice daily during the nitrite spike, and made sure I did not go more than 36 hours between applications of the Seachem Prime -- this was to keep Gerard safe, Prime only protects fish against nitrites for 24 - 48 hours before you need to reapply. When levels were higher than 2.0 ppm on ammonia or nitrite, I did a 50% water change as well as a dosage of Prime. This ended up being about every 2 days. Remember to dose the prime for the whole tank volume, not just the replacement water. I did not overdose, because I did not want the chemical to build up in the system too much. Some people say that the bacteria in Stability is not the same as the wild nitrogen fixing bacteria, and that you will need to keep dosing this weekly forever in order to keep your colony going. That may be true, I dunno. The bottle isnt expensive and it will last a long time, so it doesnt hurt to just do it at least until you run out of it. By then, perhaps you will be well established and can stop dosing it. If you are in a situation where you have to fish in cycle, as I was, I say definitely use the Stability with Prime method.

Thank you!

I did a quick clean of my tank, changed the filter, added water and this stabilizer. This product works well and fast and cleared up water in the tank quickly

It works for fishless cycling. It is not completely foolproof and the directions are more like guidelines IMHO. I started to see signs of the nitrogen cycle within a few days of following the directions. Albeit, at a very low capacity. It takes time for it to grow and adapt to the tank conditions and it is very sensitive at this stage. An ammonia spike or chlorinated tap water could easily kill it. Be sure to use Prime! Not Amazon Prime, Seachem Prime! It does not actually say that it cycles your tank in 7 days like people seem to assume. More like, it takes 7 days of dosing to ensure the start of the process, and once the process is started there is little point in adding more. You still need to add fish gradually over weeks or months which is no different than before. I appreciate the product description indicating that they have given thought to long term stability. I wish I could get a little more detailed information but I think its probably a trade secret. It worked for me and I think its a legitimate product. Your results will very per your unique situation.

Killed my bottom feeder! Never using again! I switched to this from API to cycle my tank that I have had difficulty cycling since water change. The next morning my otherwise healthy bottom feeder was dead! Be careful with this product!

Works great! My bettas and ghost shrimps are well commute with no stress to any of my fish! Great price and value vs other pet stores.
