Thanks for the update. Was curious to hear how your auto water change system worked. You weren't worried you were losing some of your fresh salt water out the drain in the sump? The concept looks great but I wonder what the efficiency losses are based on the fact that new water is being added while waste water is being removed simultaneously.

Good luck with the reassembly of the system. Looking forward to some updated pics.

I'm sure there was some loss albeit minor but this was the quick change weekly WC. For the monthly change, I would turn off the return pump which would fill the sump up to about 90% capacity, then I would remove the stand pipe and drain the whole sump leaving about 10%, the last of this water and dietris would be removed via shop vac. Last would be turning the pump in the basement filling the sump to the 90% mark again (marked on the side of the sump) and utilizing a float to kill the pump and turn the return pump back on...the skimmer and other equipment would then turn on 30min later...

Thanks. Sounds like a pretty quick system for the larger water changes as well.
