so, i've been waiting for some equipment to show up before I get my tank going. I'm going to have a good amount of light in my 20g via HO t-5 fixtures. i've been reading a bit about algea and I know that high phosphate can promote the growth of algea. My question then is, in light of not having an RO filter, is there a good way to decrease the phosphates in my tap water right off the bat?
