I've been into marine/reef for several years now, with a break of a few. Set up my current tank a year ago and had the nightmare of a long power cut 2 months ago and the temp went down to 12 degrees for a period of 24 hours. I lost some fish/anemone/coral and since then it's been a battle to control the algae. Bordering on giving up till today, but half an hour looking at my fish and how hardy they are, how stable the water has maintained, made me realise that it's worth fighting for.
So down to the LFS today with water to have a full double check by an expert. Alls well, just a massive bloom of cyano and other algae......and some little creatures I don't recognise, seems thousands of them.
not gonna let it beat me........
