Alright, a little perplexed now. I have had my reef up and running in the same tank for around 5 years now. No fish in it for 3 weeks now as they were getting too big. It is a 27 hex with a bak pak and 200 gph powerhead for circulation. Water changes with RO (not DI)water 5 gallons every 2 weeks. Fed a half a dime size chunk of Rod's food to the Duncans, Acans, Brain and Zoos every other day, and 80 watts of PCs for light @ 9hrs/day Never had a problem with cyano until now. I live in an area where there is a lot of water being used for fracturing rocks for the Marcellus Shale gas, and is dumped back into our drinking water system....do any of you guys think that that may be the culprit for the bloom in cyano? If that's the case, should the RO unit take out the phosphates? Or will should I tack on the DI? I did some big 60% water changes a couple of weeks ago to try to remove phosphates (I don't like adding to may chemicals to my tank...i.e. phosphate sponges). Any help would be a boon to the old reef...thanks!
