need suggestions on changing sand bed

[Marcus K]

What would be best for in a 10gal Refugium? I was going to use a DSB for this only as my main is 2" CC. I have found that my tank is doing much better if I vacuum twice a month. The stuff that I vac out looked like coffee and smells terrible. No when I vac its no where near as bad. Now all I need is a good skimmer and I'm set. Any one have a Beckett style skimmer for sale that is good for a 90?
