Sand

[freeless2002]

I'm just wondering. What type of filter is used when sand is used?

Same filters as gravel, except i wouldn't recommend an UGF.

I know its not my post, but I have a q,
would a reverce ugf be okay? I've heard sand can compress and become a solid mass on the aquarium bottom. is this only certain types of sand? how do you prevent it?

Really? I was under the impression ( how I got it, who knows) that a whisper would suck it up. ****. and I just put gravel in a new 20. oh well.

Here are some results of a quick search. They will probably explain things better than myself.

you can use the "search option" and use the key words "ugf", "under gravel filter" and "sand"
