Recommend: Sand Sifter/Stirrer

[walloutlet]

That's an excellent suggestion. I really haven't thought about it that way either. I wasn't planning on keeping a deep sand bed but the more the time goes by the more I am seeing the added benefit of it. I have a pretty good fuge, sustains lots of life there but that doesn't help too much for feeding a Goby when he has cleaned the sand bed out of everything.

I will add this to my list of things to try...

You can turbo charge your pod population in your refugium by adding live phytoplankton. Later on you can add a small goby.
The one inch sand bed you have is cosmetic and wont sustain an active population of sand critters IMO.
