The ideal sump/refugium

[Canuckgod420]

All refugiums are BB?
Where are you getting this info?
Everyone I know who has a dedicated refugium has a DSB.
Go with at least 6 inches of sand.

Or do you mean your refugiums are all BB?
As far as light movers go...any indoor garden supply place sells them.

I use the miracle mud in my mangrove refug but I put about an inch of sand over the top of it and havent had a problem with mud entering the system.

Ya' MY refugiums are BB, for now. That sounded like I was preaching the gospel with no clue what I was talkin' about didn't it?

I haven't heard any really negative reviews about the "mud" theory, I just don't know if the cost justifies the results. Difficult though with a relatively new product, but I was jumping on the bandwagon when powerheads replaced air stones on UG filter systems for marine tanks...yikes!

As for the sand, is "play sand" still a good option and "seed" it?

I used this instead...Caribsea Mineral Mud Substrate - 1 Gallon. Half the price and it satisfies my belief that trees need soil.
