The system will consist of the main display (180g), sump below (approx 70g) , and a remote refugium plumbed into the system (right side wall). It will be fed from the return pump and gravity drain back to the sump. This way I can take the refugium offline if needed. I also plan to plumb in a relatively easy way to perform water changes. Still researching ideas.....
Here's the ever evolving equipment list, some of which I'll transfer from my 40g.
Neptune Sys Aquacontroller Jr + DC4HD (40g)
Neptune Sys AquaSurf
3 Lumenmax Elite mogul reflectors
3 250 watt Galaxy e-ballasts
MSX250 skimmer (^^^)
Reflo Dart return pump
2x Tunze Stream 6105
2x Tunze Nanostream 6025 (40g)
Filter Guys Ocean Reef +2 RO/DI
Heaters, etc......
I've got a long way to go.
