Hey fmb, I have recently started my first hydro grow and while all my plants are doing pretty well, I had an algae scare. I emptied the tank and cleaned it before putting in new water and nutes, but what i was wondering is if i could use a fish tank filter to keep my water nice and clean. That way algae wouldnt be a scare and i would be able to use tap water in my system. my only worry is if it would filter out the nutes. Thanks for any help!
