Love my Osmolator. Until I wrecked it to with all the Apex stuff. :lol:..This tank move is now around $600 in broken equipment. Good thing my head is attached to my body or I would screw it up to.
Im looking at switching now to the duel Apex floats & the Aqualifter pump. Or is the Auto top off duel switch a better purchase for the same price.

Yea occasionally mine would run dry but nothing to long. At one point I just bought 3 replacement pumps they were failing that often. Eventually I threw it in the garbage for an autotopoff.com

I have my tank plumbed directly in to the RO/DI so its just a solenoid that turns on or off been running like that for around 5 years or so. That part works great, I have one of the newer bulk reef supply 150gpd systems and always getting 0 TDS out with the inline meter.

You two are effing crazy. Don't come crying here when your tanks crash from "sudden low salinity". :neutral: My rule is ATO container is no bigger than 10% of the system volume. If the ATO is full, the majority of the tanks' inhabitants will handle it (SPS may not). If I design the system, the sump will also hold this volume with the power off and not get the floor wet.

Guess I will go with the Auto top off duel & Aqualifter

I got the osmolator pump working by direct wiring it to the Tunze power supply. Now to figure out how the float switch turns if on/off ?

Okie. I have it.
