ok gathering some feed back.. have a large tank sps reef.. tank has layer of sand for the wrasses.. not to deep.
large sump in basement is 300 gallon round horse trough. has a plenum with sand for the past ten years. has some live rock also
thinking about taking out the plenum and going with live rock .. I would add more live rock ... and add in marinepure blocks. I run a calcium reactor and kalk reactor and dose.. so what is the downside?

thoughts..
