Finally get some coraline in my new tank

[beefus]

Too bad it's on a power head, Is this typical?

[ry05coupe]

yup. It grows a lot faster on my mp10/overflow box/return loc line. I guess it likes plastic, the flow and the fact that it doesnt get scraped every few days like the glass does.

I am excited and disappointed at the same time with this new discovery.

Mine is multiplying like mad on the rocks, nothing on the plastic though...
