Tom's Aqua Lifter question

[Lampshade]

Nice setup, seems to have worked out well.

Sounds close to what i have, walmart buckets and a couple kent float valve's. I have mine being filled with an RODI, so I added mine at a height pretty close to the sump, enough that if my tank float valve fails open (which may happen one day with salt buildup, etc.) The resivior bucket will only fill until the sump is at near max, the height of the float in the Resivior. Only issue with this is that my RO unit has to stay on(or be turned on once a day) since the resivior level's only a few inches above the fill level in the tank.
