Hi Tuni324. Welcome to Reef Central. I'm interested in an ATO for my new 20 gallon. Hopefully we'll get some good recommendations.

Thanks for sharing to everyone! Very useful info

The Osmolators have a long track record so that's what people normally recommend. There's s many newer ones now made by Autoaqua, Kamoer, Reef Breeders, Ice cap, XP Aqua, Innovative Marine, Hydor, etc., and as you've noticed mixed reviews. I really don't get why there is failure with these considering I've been using a DIY reed switch, relay, 9v battery, and a aquaclear 201 pump for nearly 20 years straight without a problem. My only guess is this fascination with using optical sensors but that is just a guess. Let us know what you decide on.
