I noticed some bright and I mean bright red algae forming under my MP40 on the sand bed and glass......


Its not hairy, and not slimy.... Its on my Mp 40 as well and I couldnt rub it off.....


seems to be contained to the corner for now but it has spread from the other day.....

I was trying to get a pic..... but under LEDS it isnt working, I will try again in a few....
