Is there any info on the effect of temp on algae growth? Link to a thread or article? Background: Tank has been up for 3 years. Had my standard various issues but never any serious algae. Earlier this year we had storms, as many others did, and my tank got down to 70.4*F. Since that time I've never really gotten it back up to the 80* or so it was before. Mostly around the 74.5* mark. Since that time I have also lost 2 Foxface and a Flame Angel. Also about 1 gallon of tap water was accidentally introduced into the system about a month ago. Now I have all kinds of stuff growing in the tank. I have replaced my 2 200w heaters with 2 300w and added a 3rd. Temp is slowly coming back up over the last few days. I have done numerous water changes but have Green hair, Red hair, Brown hair, a green I've never seen before, and red covering type, (all algae) as well as cyano growing in my tank. Oh there is bubble algae too, but I know where that came from. I have about 60x turnover in the tank with powerheads and new return pump.
