Seachem Pristine Aquarium Treatment, 500ml (001438)

Best I've used for my tank!

This did clear my long term cloudy aquarium water after dosing two times. It adds a different kind of bacteria to the water column and passes through filters. It doesnt seem to cause any issues to the already established nitrifying bacteria either.I had tried water changes and less feeding to no avail. None of my chemical checks showed anything was out of tolerance. Yet within 1 day of adding new water, the tank water always became cloudy. I doped the tank with this twice over two days and now the water is crystal clear. I'll likely continue to use this product in the future as needed.

works well in my tanks, i use this with water changes keeps tank clean

This stuff always make my water like crystal

Top notch. Works well.

Didn’t harm anything, but didn’t seem to do much for my tank, either. Maybe I should use more than one bottle’s worth.

Anything regarding this brand works well and is very gentile to my fish. I can always count on this brand and they offer a variety of products from antibiotic treatment to water conditioner, Everything you might need. Totally trust their products.

Want a clean tank? Want value for the money in a large bottle size. Want it to do what it says it will? Get this then. Works like a charm. Love how easy it is to use. Great bang for the buck.
