Hi, I'm redesigning my sump and make up water system (based on Stockmans design) and I would very much like to get some comments and feedback before I start buying and building.
Here is .jpg of the design:
The basic idea is that RODI water flows in the lower Rubbermaid stock tank and the pump (protected from running dry by a low water float/relay) in that tank is on a timer which pushes the water to the upper stock tank for 15 minutes every 12 hours or so. Hopefully, this should help keep the RODI from cycling on-off frequently. Make-up water flows from the upper tank through the kalk reactor into the sump. There is a pH controller to prevent overdosing which will shut off the water supply to the kalk reactor if the tank pH rises too high.
Flood control:
Bottom Rubbermaid tub has an overflow to waste drain at the top. Feed water is controlled by a float switch/solenoid and feeds into the tub using a mechanical float switch. Overflow would require three failures.
Top Rubbermaid tub only receives water from the bottom tub. Overflow drain installed at the top which flows to bottom tub.
Salt mixing container is filled through a mechanical float valve and has an overflow to waste drain at the top.
Sump filling is controlled by a solenoid/float valve for primary water filling from the kalk reactor with secondary protection from the float valve. I don't currently have an overflow to waste drain on the sump, but I am waffling on the idea of adding one. The sump has 25 gallons of overflow capacity. Water rise during a power outage is about 13 gallons from the main display and refugium.
Micro bubble control:
My ASM skimmer allows some micro bubbles on the output. To control that, I am putting the skimmer into the first chamber of the sump and the setting up two series of baffles to prevent the bubbles from reaching the refugium and display. I am not positive about the baffe design and would like some input here.
Thanks,
Phil
