hi guys just wondering if anyone knew of any ways to give the water a good polish without having to go down the diatom filter route. My water parameters are good, ammonia 0.00, nitrite 0.00 and nitrate 0.5. I have a wet/dry that handles all the bio part of my filter and it has filter floss above it to catch detrius. There is also a cannister filter on it from an old tank, it is underated for the size of the tank its intended for a 400l tank and the tank it on is 700l+ but it was only really to aid cycling the tank and to add some mechanical filtration. The problem is i can still see particles in the water column so i was wondering if i could fill the cannister i have now with filter floss or if you guys know any other way i could polish the water. If it means buying a bigger cannister i will, but i could just do with something a bit cheaper at the moment as with everyone money is a bit tight
