Well the eheim that would be pumping the h2o back has a flow rate of 264gph...so maybe something around 250? I know that is incredibly slow...but the main goal of this fuge is to remove nitrates, and create tang food. (Several dehydrated macros + vitamin enrichment. Coming soon to MFK for sale section
)
That being said, my only concerns are power outages ect...what happens then? I will probably end up frying out my pump.
I would look into doing an ATO whenever the cash presents itself. Its very nice...
Also, flow rate of the overflow doesnt have to match, just so long as it exceeds the output of your return pump. The overflow will only drain at the rate that water is being pumped in.
With that said, I dont know if you can throttle the return on your canister. If its a magnetically driven pump, you can put a ball valve in.
If you get a good overflow, the siphon will restart. The key is to never let the water level on the back portion of the overflow to become lower then water level in the front of the overflow, which is incorporated into the design of overflow. The actual bulkhead/prefilter assembly would need to be offset higher for that to work.
This is taken from lifereefs website. You can see how the siphon tube and acrylic plates reproduce this.
