Seachem Stability

I was skeptical about adding bacteria to a brand new marine tank, but after a week of dosing, my ammonia and nitrite readings finally hit zero without a single fish loss. The fact that it works for both freshwater and saltwater setups made it a no-brainer for my nano reef.

My 55-gallon freshwater cycle crashed after a water change, and this had my ammonia levels back to zero within a week. The bacteria seem to establish much faster than any other bottled bacteria I've tried. Definitely saved me from losing my cichlids.

I set up a 20-gallon saltwater tank and added this right after the live rock; the ammonia never even spiked past 0.5 before dropping to zero in four days. It handled the freshwater-to-marine switch without a hitch, and my clownfish stayed calm the whole time.
