I am planning an using a phosphate remover such as Phosban or Rowaphos to help control algae on in my 30 gallon tank. My question is two part, first is there a specific product found to be superior or do they all do basically the same thing? Secondly can I add this product to my activated carbon bag or place in a separate bag in a high flow area of my sump? (my setup really does not allow for a reactor.) Any thing else I should know a before I use this? Thanks
