Seaserpant, anenomes do sting. And they can sting corals as they wander around the tank looking for the best place to 'live'. And in the act of stinging a coral, if the sting is severe enough, the anenome can end up killing a coral. So its tricky having anenomes in a reef tank, but once they find a spot they like they really dont move around too much. I make sure to remove any extra anenomes I have just to prevent them moving away from each other and into my corals.
erikages, I just did a quick test about a week ago. Nitrates- 5 (or under 10) and phosphates - 0. I tested my calcium too which was at like 600 or something, off the charts, and its a new test kit so i gotta see if its off. I really can't imagine its that high. Other than that I havent really tested anything. I'm pretty lazy when it comes to that kinda stuff.... Raf will attest to it. My corals will tell me when I need to dose and/or do a water change.
I was running a UV sterilizer for a couple weeks just to combat a little ich outbreak that occurred after the addition of a couple gobies. The water just looked great after that, but since I dont have a sump the pump in the tank was an eyesore. I always run carbon, and change it out once a month. I think if my diatoms relapse then I'll throw that UV back on again.
