  • Crystal clear water
Water clarity improved within a day of starting to use during weekly water change. Impressed so far! I’ve been using this item a couple of weeks and results are striking, crystal clear water. Wow!

  • Great product and price
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. ... show more

  • This product jump starts the all important nitrogen cycle in my fish tanks.
I am way too impatient to wait a month before adding fish to a new tank. This product gets my tanks off to a healthy start and keeps it in balance when added with every water change.

  • It's indeed a life saver (rookies read this)
I had a sudden Nitrite spikes due to warm weather, it really warmed things up and nitrites just kept coming back in high high levels in under 4hrs after a 60% water change!! On the second day, the bacteria from this product established itself, and completely ate up all nitrites and for the first time my nitrates are much lower too!!! I use tap water, I process it in a 5 gallon bottle before adding to my 10 gallon aquarium. I process with API super strength conditioner dechlorifier (1 drop per gallon no more no less if you want your fish to be safe, 5 gallon bottle, hence the 5 drops) and then i mix and then I wait 1hr. Once thats done i use a syringe and inject 5ml of Quick start into the water as well. (1ml per gallon, not drop) I mix and then wait an hour again, that gives time for the bacteria to colonize completely. Sometimes I just set it aside for days after doing all those things because I don't need the water in the moment, by the time I use it, it will be very dense with healthy bacteria. Overall I'm very very pleased with this product, I had 3 shrimp die from nitrites already, this product is a true hero, saved the rest of my shrimp and fish. ... show more

  • Check your actual water volume
If you are using this to help cycle a tank, take the time to figure out how much you need per day/week over 6 weeks for your specific aquarium. It does work and I would use the whole bottle in the time it normally takes to cycle. In other words, this isn't a product you "keep a little for later."

  • Actual Life Saver
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. ... show more
