What is building up on your sand that you think needs to be vacuumed?
Well currently I have no clean up crew as I am doing hyposalinity for Ich.
I do have some seaweed that the Tang rips off and does not eat,it just settles to the bottom.
My biggest reason is I thought I might need a vacumm is while doing the hyposalinity I have so far replaced 15 gals. of water in a 29 gal. tank and my NitrAtes still seemed a little high (40)
