A different sand question

[allan]

John was explaining to me the other day that he uses a slow siphon vacuum... When the sand gets halfway up the cup he pinches the line and let's it fall back down.

I've had dragons and diamond gobies. The former picks up sand and drops it from higher up in the tank. The latter takes in the sand and drops it while hovering right over the sand.

Gobies will keep your sand clean, but there is a chance if your tank is big enough that they may ignore a spot or three.

There is also the fact that a pod population living in the sand may be nonexistent with a goby.

I don't know how vacuuming a sand bed would affect pod pops. I've only done the sand vac when I had problems with cyano. I have spots where it shows up... But I don't see it on the sand because of the goby and conch... I think.

I love my Pair of Diamond Gobies. I had an Adult from Gabes and added a Juvenile from Phenomenal and it has been fun to watch these two

I also have nassarius snails and a diamond goby and my sand looks crystal clean.

What about that funky tan stuff that builds up in your sandbed?

I've never vacuumed substrate in a saltwater tank. I have thought about adding something to sift it, but I don't like snails and there is usually a downside to everything.

I just let mine be. I dont get algae on it because I run an ATS. I do have an engineer goby but he has already made all his tunnels under my rocks awhile back.
