mold or fungus on new gravel covering old gravel
Posted: Thu Jul 04, 2013 9:27 am
Hi
I have purchased new gravel to go in my fluval chi, I thought I'd save the existing gravel and put it in tights and keep it under the new gravel, but the new gravel above the old gravel has got a film of grey fungus on it.
I have siphoned most of it off. Should I take out the old gravel and give the new gravel a good wash in tap water before putting it back in? I think it must have something to do with covering the old gravel, suffocating the good bacteria and I want to get some shrimp but I can't with this fungus, I've never had it before .
