Auto Water Filler Controller Auto-top-Off System Water Level Controller Adjustable Valve Mounting for Aquarium Pet Supplies

Was looking for a auto shutoff float that's small enough for a 7 gal Nano aquarium and this one works well though unlike the larger versions the position of the float is one solid piece so you cannot adjust the water level if you want to have it lower than approximately half inch from the rim.

It definitely works well. I took off one star because I had to add a clear rubber cabinet door “bumper” to the inside of the clamp so it could fit properly on the lip of the 5-gallon bucket I was using this on (for making RO/DI water). Once I did that, though, it was perfect!It’s not too huge, but still would be an eye sore in an aquarium. I would HIGHLY RECOMMEND to the MANUFACTURER that they try to make a BLACK version of this device. In an aquarium, that would render it much less noticeable.

Works great

Issues with the orings not sealing the pressure, I used a rubber flat washer and that did the trick.

Excellent cost-benefit

The water level is not adjustable. Or I used it wrong because there is no instruction in the package.

I'm using this on the top off tanks for two Red Sea aquariums. All good.

Todo está perfecto. Mil gracias Amazon

Works excellent bit adjusting water level makes you iffy if will snap the arm

Not the sturdiness apparatus I've ever encountered. But it does the job.

Works good, only installed 1 month but works good so far.
