Yes, things have grown a lot.
I had to frag the frogspawn on the far left as it go way too big.
could you provide a quick and dirty explanation (no diagram necessary ) of the flow of water through the system?
The sump consists of 2 x 44 gallon Rubbermaids connected with a big bulkhead connector. The first has the skimmer (ETS 800 gemini with an Iwaki 55RLT to drive it; inlet and outlet in this sump), heaters, water cooling coils, and water returns from the refugia.
The second can has a lot of left over live rock, and the main pump sending water back out.
That pump (actually 2 Iwaki 30 RLXT pumps in series) send water to the main tank, a second 90 gallon reef aquarium in the basement, and through my ozone reactor.
The water going upstairs to the main tank returns to the basement by gravity,a nd enters the first of two refugia. It leaves that one by gravity and enters the second. It leaves that one by gravity and enters the first sump.
