FEEDBACK needed on 400g DSB build with flow chart

[DOGGIE750]

Hello Reefers:
My 400gal DSB build has been slow as a snail in progress but it’s moving. My goal is efficiency in maintenance and energy. All feedbacks to guide me are all welcome.

Please see the attached flow chart for your review.
Tank: 96 x 31 x 31
DSB: 5”- 6”
Overflow and output: 2”
Returns and inputs: 1 or 1 ½”
Sump 3 stage ( 1 Cryptic zone, 2 PS and Ca xtor, 3 clean water)
Clean water from 3stage to IWAKI pump then directs to
 Display (Return 1)
 Surge 1 (Return 3)
 Surge 2 (Return 2)
IWAKI pump will be located in the mid-section (ideal spot to maximize flow and minimize differential)
Valves will be installed to regulate and isolate as needed
Power supply will be only for the ff items below:
 IWAKI pump 1/4 hp. Do I need 2 pumps? I have an extra one for back up.
 LED overheads
 Heater (titanium) in sump… any suggestion what watts?
 PS pumps

Battery operated:
 Digital thermometer
 Auto feeder


I know it’s vague but just wanted to reach out to the SMEs before I step on the gas.

MUCH THANKS

What are you planning to keep in your display tank that would need a 5-6" deep sandbed? If there is no particular purpose I would suggest you keep the DSB outside the display tank in a separate container. That way if it crashes it won't bring your whole system down with it.

Thank you Dave. The live stocks will be DSB friendly. Unfortunately, DSB will be in the main tank. The tank has partitions that I need to cover with sand.
