Product Recommendation - Easy, affordable optical ATO

[TX_REEF]

I rarely do unsolicited product recommendations, but this auto top off I use recently stopped working, and when I contacted customer support, they sent a replacement no questions asked. For a 2-year warranty, easy install and $50 at the time of writing, this is a no brainer. Highly recommend.

I have the same one, and it has been good so far. The little pump has no problem pushing water up almost 4 feet into the back of my tank. I highly recommend it as well.

Good to here they are standing behind the warranty. When I buy less expensive items from amazon I usually treat them as disposable.

I use a few versions of this one (AutoAqua, Magtool, etc). Mine have all been flawless.

About a year ago, I did replace one that was 2+ years old. Not because it quit, but because they're cheap, and it is good peace of mind. I still have the old one in a box to use as a backup if I ever need to.
