$300 ATO help me find a better solution please!

Tried to take a video but I think it was too large. Blue RO line comes through stand to solenoid, which runs to float switch in return bay. Sensors control high and low water level in the return bay. I do have an FMM which powers my sensors. The solenoids plug into the Apex Powerbar.

Since you already have lines run, couldn't you just use a "fish tape" and "fish" the cords through the holes that are already there?

Something like this?

unfortunately not used pex as a case and its a S shape and 4 1/4' RODI tubes barely fit.
I think the avast might be the best solution for me. I can run it stand alone or hooked up the the Apex have not decided yet. advantages to both I guess.

humm this is interesting...but why do you need 2 solenoids? i got get that part.

Cheapest and most reliable is probably a Tunze Osmolator with AC outlet and a Mag 12 Pump necked down to 1/4 tubing.

The 2nd solenoid is for my auto water change. I used the same concept. This is my saltwater reservoir.

I use a DOS to do the water change every night at 4am.
