There's about 100lbs of live rock in the DT to do some bio filtration.
Sump filtration setup consists of:
Section 1: Water flows into this section via two 1" pipes from the DT. This section houses a Hydor 700 skimmer and a pump that pumps water into two phosban reactors (1 for carbon and one for Rowaphos).
Section 2: in the middle of the sump is the return section
Section 3: is my refugium which has its own 1" feed from the DT. In here I have 3 inches of sand, a layer of live rock/rubble, then a layer of macro algae (which doesn't seem to grow that well
.. not enough nutrients I guess.. )
No filter socks or mechanical filters.
