I think some people just have trust issues

my DIY auto top off consists of three float switches, two on my sump (one for redundancy) and one in the reservoir. 5v runs through these and actuate a relay for my pump. I would never trust it if I connected the pump directly to them. It works great so far. Almost a must with a skimmer

I love mine. It is fed by a 5g bucket so even if it goes haywire (never has and hope never will) adding 5g of fw to a 165g with 90g wide sump will not have a major negative effect. I top it off every 4-5 days (glass covered display). This would not have worked on my 210g with 75g sump (all open top) cause I lost 3+g a day on that system.

I have one of these:

Its has never failed. Used to use a Tunzie, I was buying new pumps for it every 3 months until the controller gave up.
