Why did you pick this product vs others?:Does what it’s suppose to

Stability helped me start and establish a brand new 55G tall from scratch with only one fish departing to the Golden Pond in the Sky (loach swam up the intake into the filter impeller...messy). From day one I did daily testing with the API kit and made an Excel spreadsheet of the data. There were very small, irregular ammonia spikes at the 2nd/3rd week, but not into the "danger" zone and slowly decreased to 0ppm by the end of the 4th week. Nitrites and nitrates increased from the 3rd week and then hovered at a "very acceptable" range below danger zone and then gradually decreased to ~0 ppm for nitrites and ~20ppm for nitrates by the 5th/6th week. The results I got from the test kit were evaluated against a U of Florida's chart (I am a bio major) of Total Ammonia Nitrogen Toxicity (using pH and water temperature as the other parameters), and were in the range that is deemed not dangerous to FW fish for a short term period. With the results of these API test and my personal experience, I would definitely recommend and have been using Seachem Stability as a "jump start" product to establish the important biological filter in a FW aquarium or to boost or supplement the already existing bio filter in an established tank. For those interested about my experience, see below for in depth details.Products used:-Seachem Stability-Seachem Prime-API FW Master Test Kit1st week:IMPORTANT: FOLLOW THE DIRECTIONS FOR THE FIRST WEEK'S DOSING SCHEDULE BASED ON YOUR TANK'S VOLUME.Added 7 Zebra danios. These are hardy fish and can survive a newbie's foray into fishkeeping and hopefully any mistakes I make.First day: One capful( 5mL) for every 10G of NEW WATER, so 5 capfuls.Days 2-7: One capful for every 20G of water, so ~3 capfuls EVERYDAY. Added 4 black Java loaches/khuli loaches on day 3.Note: Directions says you can add fish/inverts immediately and at any time as long as you follow the all-important dosing schedule above for the FIRST week only.NOTE: After first week, one capful for every 20G once a month, or with each water change, or introducing new fish, or medicating.2nd week:Added Dwarf gourami and 3 Albino cories. Did 25% water change with Prime, then dosed with 3 capful of Stability, which is the dose for ~60G.3rd week:Added Bristlenose pleco. Did 25% WC with Prime, then dosed with 3 capful of Stability.4th week:Added 3 more Albino cories. Added 1teaspoon/10G API Aquarium salt to counter increasing ammonia, nitrites and nitrate spikes.5th week:Added 5 more loaches. Did 25% WC with Prime, then dosed with 3 capful of Stability.6th week:Added 2 Amano shrimps. Did 25% WC with Prime, then dosed with 3 capful of Stability.4 months later:3 Bamboo shrimps, 2 Amano shrimps, 9 Loaches, 6 Cories, Dwarf gourami, 7 Danios, BN pleco, plants. All fish/inverts growing and healthy. I now only dose 1 capful of Stability with each 25% WC, as my biofilter is now well established and API tests show it doesn't need 3 capfuls for every WC. Thanks Stability!

Great quality

I use seachem products on all of my aquariums, this is the best value for your money when it comes to water, cleanliness and water clarity. The size of this product helps with large aquariums and the smell is not that bad.

I used Stability to kickstart the cycle on a new tank and it worked faster than I expected. I dosed it daily for the first week like the bottle says, and by day 5 or 6 ammonia and nitrites were already dropping. I was also using bottled ammonia and keeping things consistent, but I do think this made a big difference. Water stayed clear the whole time and there was no weird smell or cloudiness. I’ve used a few other bacteria starters before and this one seems to actually do something right away. Might not be “instant” like some people say, but it definitely sped things up. I’d use it again for sure.
