37 gal column conversion to AIO with foam/rock wall

[Cubeman]

Here's where I am at with the equipment for this build:

Aquarium specs:
37 gallon Marineland column aquarium. 20’’ long x 18” wide x 24” deep, black trimmed. Converted to an All in One (AIO) with a 14” x 4” equipment/filter area with 2 returns along the back left wall. This leaves 32 gallons of tank space.

Return pump:
Tunze Silence 1073.008 (210gph). This specific pump was purchased for its extremely quiet operation and low electrical demand (8W).

Flow:
Not purchased yet. Thinking of 2x Hydor Koralia 550 on timers.

Lighting:
Not purchased yet but am going LED with this one.

Filtration:
I have an old Red Sea Prizm HOB skimmer which has sat in the garage unused for 10 years. I designed the AIO compartments to accommodate this and like its very slim profile. I will be using it until it gives me a reason not to. My stocking is very light compared to most so the skimmer is hardly a requirement for this tank.

1x Two Little Fishes Phosban Reactor 150 with phosphate removal media.

Controller/Monitors:
Reef Keeper Lite

PinPoint pH and Temperature monitors

Heating/Cooling:
500W titanium heater controlled by the RKL. Seems like overkill but i) I already had it on hand ii) my house gets cool (mid 60s F) at night iii) the return pump circulation is quite low

Pacific Coast Mini Chiller (1/13HP) with 80gph throughput. Digital and adjustable so no need to run off the RKL.
