apex float switches

Sorry to hijack, what float switch are you all using?

I use the Avast pressure float switch for ATO, but wanting to add a float switch for my filter sock section which is little less important, so would like to find one cheaper.

Saw these on eBay, will these work?

I'm using the ReefKeeper Float Switch Kit in the sump, just because it came with the brackets already. And the Deluxe Madison Horizontal Mount Float Switch for the ATO bucket. All from BRS. I don't see why the ones you are looking at won't work though.

First, most float switches can be reversed by removing the clip below the float and flipping the float. That will change the float from normally open to normally closed which I think you are aware of.

That said, 1 float will control ATO and I would suggest that the action or pump turns on when the float is closed like you were suggesting. That way if the switch gets blocked by a snail or gets unplugged, your ATO pump won't turn on and flood you system.

Ato Pump programming:
Fallback OFF
Set OFF
If SumpLo OPEN Then OFF
If SumpLo CLOSED Then ON
If ATOlo Open then OFF (This could also be IF ATOLo Closed then OFF depending on your logic)


As for turning off the return pump when the ATO reservior is low, I am not sure I agree with that logic. If the ATO reservoir is low, I'd trigger an alarm but not shut the return pump off.

Totally understand how to change the float from a normal state of OPEN vs CLOSED. I was just trying to keep things as simple as I could... BTW saw your post about Tunze Pumps programming and THANK YOU! Exactly what I was trying to do!!!!!!

Spend the extra money and get these, no need to scrimp on a rather important safety feature.

How did you rig it up? I was looking at getting some of those but it sounds like finding the nut to secure it to a bracket is hard to come by.

I will take more pictures tomorrow and tell you how to build it (ie. what parts you need).
