i'm changing from a fish only tank (120gal) to a semi reef(mushrooms, polyps and maybe some hardy coral).in about 3 weeks i've put about 35lbs of cured l/r & 60 lbs of l/s.i have some algae growing on the back walls of my tank(green). do i need to remove that or will coraline alge take over? i also would like to know what is an exceptable level for nitrates ,i seem to be having a little trouble getting them below 40ppm. i have an r/o unit for water replacement.the fish i have are: 1 grey angel..1 flame hawk.. 1 rainbow wrasse...1 coral beauty.. 1 brown scopus tang.. 1 naso tang..1 niger trigger.sorry for bring so long winded.
