I have a 20 gal
oceanic sump (manf date of 2004) below my 72 gallon bf. It has a big box that was loaded with bioballs, that I removed, It has 3 separate glass lids which are a little annoying to use.
I want to use chemipure and purigen, should they go before or after the refugium, does it make a difference as far as nutrients for corals?
I already added a piece of acrylic to increase the depth of the refugium area, as it was only about 6" deep. I have a dsb
in display, should I do one here as well? I have live rock in the sump and chaeto, there is no sand.gf
this pic was before I cleaned it...I'll take another soon...
