Okay, so I had a minor cyano outbreak this week. I found the source, which is good. My DI filter had gone south, but I had used the system for my last water change without knowing. That, and the other parameter that has changed in the last couple weeks is I upgraded from a crap 30W fluorescent to a coralife lunar 196W. So, the cyano came out and I did a 50 pct water change today using distilled water from the store which tested 0 for phosphates. After the WC, my water tests 0 for nitrates and 0 for phosphates (sera tests, I trust them with my life now). Where is this crap coming from? I have good water flow, 200+ gph over the affected area and 200+ gph over the back of the tank with another PH. I ordered the nassarius snails from ebay, but they'll take two weeks. I also siphon cleaned my DSB today (I know, a possible no-no), but it was a mess. I only siphoned it down to about 3" of the total 7". What am I missing here? As of 8:00pm it's already back in that part of the tank. Oh, and the other param change is that I put a chemi-pure bag in my emperor about two weeks ago (when I got the lights). Any help is, as always, appreciated.
