Im trying to ID this strange white web like organism that has turned up on some Java Wood in my tank today. The closest match is Physarum or slime mold. Does anybody have any experiance of this and is it harmful to fish?
This algae has been showing up in my tank recently. I run a 20 gallon tank, 48 watts of t5 lighting, injected co2 and fertilize with aquariumfertilizer.com's Macro Micro Nutrient Mix.
I also run a UV sterilizer 24/7 that I initially installed to combat green water.
This algae (bacteria?)...
