Hi all, Need some urgent advice! I got home today to find that my anenome had died and was seriously rotten. All was Ok when I last looked at the tank last night (anenome was still open) and I left this morning before the lights had come on. Got back this evening and found a disintergrating anenome which serious contaminated the water as I tried to get it out of the tank. My question is what now? I will only be able to do about a 25L water change tonight (system volume about 350l). The water is serious nasty. Any suggestions?
