FluvalWaste Control 250 ml

Excellent stuff my water was really really chalky and this stuff cleared it overnight looks crystal clear.

Been using this for years and I'm always happy with my water quality. Good deal when subscribing.

The only reason this isn't getting 5 stars across the board is that because when I got it it says in the small print on the back of the bottle thst if you don't use it with another fluval product it can cause an ammonia spike. I then had to go and buy the red bottle too. I don't mind having to use both products but it would be useful to have been told this in the item description. Good job I read the small print of I could have killed my fish. I've been using it for 2 weeks now and am starting to see a small difference in the substrate.

ideal for cleaning filters

Im just a novice but was pointed in the direction of Fluval, don't think I will change to anything else now, great value for money also, does exactly what it says, couldn't recommend highly enough to anyone, fantastic brand.

The water quality improved and the filter seemed to excel. The fish are healthy and water is clean.

I used it couple of times and I can’t tell if it makes a difference at all. It’s a hype in terms of brand.

Fluval a trusted name. Tank was a bit messy but seems to be doing its job as tank is cleaner now and clearer.
