Mold(?) in cycling tank
I inadvertantly added in mold(?) into a new cycling tank. The only things in there are 1 blyxa, a few stems of rotala and HC.
I found the source of the mold, which was a bottle of DIY TPN. I saw stuff floating in there, but didn't think it would grow in an actual tank. So now the mold is growing in 1 or 2 areas (~2cm diameter circle) on the substrate (tahitian moonsand). It also grows on the silicon.
I tried dosing some extra excel, but nothing. Any ideas on what to do?
