So i have just completed a fishless cycle of a 10 gallon using a prawn (until it grew hair and I removed it) and then flake food for the remaining week of the cycle. I did a 50% water change last night and did a thoruogh (I thought) vaccuming of the rocks to get all the moldy and decayin fish food up. Introduced two cories this morning and they are doing swimmingly
The problem... these guys are kicking up all kinds of gunk I must have missed when cleaning lat night... what should I do? I'm afraid to get back in there messing around becasue I don't want to stress the little guys any more than they already are today. How bad is it to have some "gunk"still in the substrate?
