Red Cyano outbreak again

[jataft83]

Hello all!

My tank has been established for about 4 months now and I am still getting Cyano outbreaks and red slime algae. I use RO/DI water, i feed 1 time every 2 days and I drain the frozen food in a separate container. My phosphates are at .25ML and my Trates are 0. Any ideas?

What do you have in your tank?

1 small yellow tang, 3 small chromis, 1 black cardinal, and 1 fire fish

as you have no corals shorten your light times right down,this should help,also how is the water flow where the cyano is

Tomorrow I think my Koralia 750gph should come in tomorrow. Will that help remove dead spots? right now i use some generic Powerheaders.
