Wow product

Goldfish is known as most messy in terms of waste producer. But I am pretty much sure, if you want to get relief from changing water frequently... Recommending to use it with prescribed volume. You will all be feeling happy as I am. By the way, live bacteria spreads and works better only if water gets proper aeration. Make sure to use pump always,...

Does what it says...

Good quality product. Reduced aquarium maintenance after few usage. One can make out from filter and water smell. Both become almost odourless after regular use as directed.
