“I initially bought to control my Diatom bloom and never thought it would actually work! It does!!! I put 5ml in my 200L tank and within days it were pretty gone. Yes it is expensive! But it works and it should really be used every two weeks or weekly if your tank has a series algae issue. There are plenty videos on you tube regarding this product and I have to say I'm well impressed. So if you are looking for product to clean you rank up and you can afford the initial outlay then 100% this is product for you.”
