nitrate and nitrite on point 0
ammonia perfect
salinty 1.023

phosphates was high a while back then fixed it now. good no according to local fish store.

When you say red algea I assume you mean Cyano bacteria, does it grow all over or just inside of caves or between rocks and other areas of low flow?
Also what was the source of your phosphates? Good test results does not always mean problem fixed if you haven't identified a source such as food or tap water then the cyano and other algea may just be using up all of the available phosphates.

Also what size is your tank?
