GOOD GOD!!! This is getting rediculas!!! You two guys should really just leave each other alown.
Nate, I have only done 1 water change in the last 6 months in my 165 so does that also mean my tank is doomed? I don't have alot of SPS but I do have a few. Everything in my tank is thriving so it's safe to say not every tank needs bi-weekly WC.
MarkoD, I also agree with danillas last post. It dose seem that when my cyano shows its ugly red face it is in a higher flow area. I had it really bad for a long time until I started to make changes to my system but not to battle the cyano. I added carbon, GFO, pellets, changed my MH / T5's to LED's & got a bigger better skimmer. Now I can't really say what if any of these helped battle the cyano but I do see it more frequent when my pellets get low, does that mean anything.....I have no idea.
To sum it up make a few changes that don't cost a lot of money. Try switching up you light cycle, break it up into 2 sections of the day for high light periods or shorten it. Syphon out what you can, don't blow it off the rock and hope to catch it all in the water column
