Auto Top Up Failed Again :(

[lastlight]

i'm shocked the tunze pump has failed for you like that. i never let mine run dry which i think is the key and all the ones i've run over the years have worked flawlessly.

I'm even more surprised because I have let my Tunze ato pump run dry weekly for about 4 years and it still works like a charm.

Kent Float Valve

I use 2, 1 in the sump, 1 on RODI outlet. 5 or more years now, and never once over filled my tank. I have an electric solenoid on my RODI tank for if my sump overfills i use as a backup. The electric shutoff has failed at least twice now when i'm cleaning the tank and it doesn't shut off the solenoid.

In the end, Crappy float valves have been the most reliable.

And I bravely topoff from a 90g tank. Think this is my 5th osmolator and no problems.

Love my Osmolator. Until I wrecked it to with all the Apex stuff. ..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.

You two are effing crazy. Don't come crying here when your tanks crash from "sudden low salinity". 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 ?

[Doug]

Okie. I have it.

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.

I ordered them in bulk (10) from the manufacture over seas. I can try and find out the brand name if you want

With no moving parts they are awesome. I made two different version. One uses a float at the backup sensor and the other uses an optical sensor


I like my salinity precise
