Hello Simon,
Yes i have seen your build thread and it is quite an impressive build. Can you give me a complete list of all the equipment you are using? Also what fish do you have?
Here is my list of equipment for my 125 gal tank starting from the sump to the canopy:
30g 12x16x36 sump with custom baffles to create a PS, fuge, and return sections. I could have used a longer (>36") sump given the space that I have in the sump.
BM Nac 7 protein skimmer
Blowhole 1450 return pump
GEO 612 calcium reactor with regulator and PinPoint PH controller
Two LF 550 reactors for GFO and AC
Aqua 27W UV light
14W PAR 30 LED light to grow cheato in fuge
9 gal covered plastic container for top off water
Aqua lifter pump for top off
Two MP 40WES for flow
Two Eshine CREE 48x3W lights
A autofeeder
Two 120mm PC fans on top of canopy for heat control
The whole system is controlled and monitored by a ReefKeeper Elite controller with 3 PC4 units
With this setup, the system can run on itself with no intervention for 5-7 days, or longer if I open the RO to continuously refill the 9 gal top off water container. I chose not to do that in case the shut off valve malfunctions while I am gone.
As far as fish, I have a 6"Royal Blue Tag, 1Yellow Tang, 3 Blue Chromis, 1 Flame Angel, 1 Cinamon Clown and 1 Magnificient Foxface. I could have add 1 or 2 more fish but the corals are doing so well that I don't want to add more bioload.
