I have very bad algae problems i have tried many things. i currently have like green grass every where in my tank algae is growing on top of my corals. i have a lawn mower blemmy and a red flame tail tang to try and help with the problem but its just growing more and more. i have had my water tested at the LFS they said it was perfect no problems i am only using water from the lfs's system. i have started vodka dosing just a cap full a day. i am running 2 250w mhl 4 t-5 56w. and a 4 t-5 56w on my refuge. running mhl for only 6 hours a day down from 9 when the problem started. i am so tired of looking in and seeing algae please give me advice. no phosphates i have checked.
