5.0 out of 5 stars Actual Life Saver
Reviewed in the United States on March 26, 2024
I could not for the life of me find out what was wrong with my tank for like 2 weeks. Fish were sickly and water changes only worked for like 1/2 day-1 day. This fixed it and recycled the tank, giving new life into the environment. It is like and instant reset to the bacteria and water cycle. Definitely recommend to anyone struggling with the water changes. P.S. Careful though I (PERSONALLY) have found that after the initial dose and maybe a subsequent one to BACK OFF with this and put it into storage as it throws things out of whack with continual use.

5.0 out of 5 stars Great product and price
Reviewed in the United States on April 11, 2024
I really liked this product compared to other water treatments/biostatistics and the price is pretty cheap for how much you get. My established tanks water quality improved after a week of using and water was crystal clear. When I used it after setting up a new tank it helped with the "cloudy" start up stage and prevents new tank syndrome which any aquarist really hates. The bottle doesn't leak or drip and the cap doubles as a dosing cup.
Really great product, does what it says and you get a lot for a great price compared to other brands.

10/10 essential item for my freshwater aquarium. Keeps my betta fish and tiger barbs safe & limits toxic ammonia and nitrate. A must when setting up an aquarium, prevents fish loss, contains live nitrifying bacteria to help maintain an active biological filter in an established aquarium as well. You use it when starting new aquariums and also when doing a water change.. or whenever ammonia or nitrites are present in the water. Recommend 100%

5.0 out of 5 stars Fixed my cyanobacteria issue!
Reviewed in the United States on July 8, 2023
Last year I made the conversion to planted tanks and ever since then, I have been battling cyanobacteria in my 75 gallon tank. Ammonia, nitrites, and nitrates were always great, but within 1-2 days of an extremely thorough tank maintenance session (1-2 hours of cleaning plants, wood, walls, rocks + water change), the cyanobacteria population would explode. If I didn't address it right away, the plants, substrate, walls, heater, and filter would be covered in sheets of cyanobacteria. Take maintenance every 1-2 days was not very sustainable.

I tried feeding less, feeding flakes vs crisps vs round pellets. Some types of food exacerbated the issue. Pellets and the premium gel food helped combat the growth of cyanobacteria but I still had to do tank maintenance every 3-4 days.

I tried completely resetting the tank using the existing plants (cleaned) and swapping wood for rocks. I tried adding $300 worth of plants, in addition to what was already planted. I tried moving plants and decor around for optimal water flow so there weren't any dead spots.

I tried moving from a canister filter to an external filter. Then I upgraded to a higher capacity external filter to get better water flow in the tank.

I tried treating the tank with different products, specifically formulated to address the cyanobacteria and although it would keep it at bay, once you stopped using the product, the cyanobacteria would be back in full force.

All of this was expensive and futile because the cyanobacteria always returned with a vengeance. Of course, no one could give me a definitive answer to the cyanobacteria problem. I scoured article after article, frustrated that I couldn't find a solution that actually worked. And believe me, I spent $1000+ over the year trying a number of different solutions; none of them worked permanently. I was seriously rethinking my fish hobby when I stumbled across the solution.

I picked up Quick Start for another tank that I wanted to rebuild. I happened to be doing a water change for my 75 gallon tank at the same time and I accidentally put Quick Start in my 75 gallon tank. No biggie, I thought. Wouldn't hurt and I didn't want to waste the water. In two days, I noticed that the cyanobacteria's growth had been stunted. It was growing about half the speed it normally did. The next water change, I used Quick Start again. I didn't understand - my levels were good when I tested them so I didn't think my bacteria levels were low and I never thought to use Quick Start as a result.

Over the next few weeks, I kept using Quick Start in my water changes, I got a bunch of snails (freeloaders from my plant purchases), and I stopped vacuuming the substrate so thoroughly and now the cyanobacteria is 95-98% gone. I only occasionally see it on the walls and I can push my water changes to every two weeks, no problem.

I think I owe my sanity to Quick Start.
