[WhatReef]

if i was you i would invest in some more flow in your tank that red slime is a good sign that your not getting enough flow and also i would try aiming your power heads and returns if different directions ever once in a while to change to flow a lil cause on a real reef the flow is always changing and is doing that i thing will help get rid of the red slime i find the more flow you have the less algae and red slime you will have, have you ever considered a wavemaker.
