By request here is an update and photos of the equipment running the tank.
I have a JBJ artica 1/10 chiller hooked up to cool the tank during the warmer months and for when the MH heats the tank too much
Here is the sump. I have the return going into a 100 micron sock in the first chamber. The first chamber has a marineland utility pump 900 feeding the BRS carbon reactor (hung above - upper left) which returns into the 3 chamber. The SRO XP-1000SSS skimmer is hooked up to the CO2 scrubber through the silencer. This elevates the O2 in the tank and keep the PH stable between 8.1-8.4. There are 2 Ebo heaters also in the first chamber.
Second chamber is the fuge consisting of sand, rubble, chaeto, and a mini-jet 400 for circulation. It is lit by an AI nano LED.
The thrid chamber has the float switch for the ATO which is ran by a aqualifter pump and the RKL. The return pump is the SRO Water Blaster 1000. This was the best pump and the most SILENT I could find and test. It is very much worth the extra price tag.
CO2 Scrubber, ATO reservoir with Kalk, and carbon reactor
Tank circulation is done by an MP40 and MP10 hooked up to a battery back up. All electronic controls, temp, and PH are managed with the RKL.
Lighting is by a Giesemann Infiniti 24" 250w MH 4x24w T5 fixture. Giesemann makes the best MH fixture you can by IMO. I have retrofitted it with 3 moon light LEDs that reside in the front T5 housing. The moonlights are wired in seamlessly and you don't even see them.
T5s only on
