Been cycling my 8 gal nuvo bare bottom for about a month now and there is some sort or algae building up on the pvc I have in there idk if it is diatoms or what but is this normal
Yeah, no worries. I use a cut-off piece of poly filter pad like a sponge and wipe of the pvc, walls, bottom, etc. Usually clean it once a week during water changes for the fish.
