ato

Hello fellow reefers! I am looking at a gravity fed ATO for my 140 going into a float valve. Is there a reason why people don’t put the ATO on a slow drip with a quarter turn valve? It is something that could be dialed in and adjusted for seasonal changes? I feel like it would be more...

Upgraded my first tank which is an evo 13.5g to a waterbox 50.3 AIO. Now, I need to l find my sweet spot in the waterbox. Just need a little advice on how to flow the back chambers right & how to run an ATO. I finally got the back chambers down to where the water is flowing and breaking surface...

I set up a used Red Sea Max E260 a few months ago and the seller gave me the pipe kit for the sump (no sump). I have never had a sump before and have no experience with plumbing but I wanted to give it a try anyway. Equipment I found a good deal on a Trigger System Triton 26 v2 that fit nicely...

Hey everyone, I've had my 3155 ATO for about 10 months and recently it won't start the pump when the water level drops. This happens once everyday, I've found that nudging the optical sensor into the water for a second then moving it back helps, and it will work for serveral times until next...

I have a 20g saltwater aquiarium. No sump, but a nano skimmer. And I came across the reef pi and thought it could greatly improve the stability. I've seen people build ATO, but none of the ones you can buy off the shelf seem to include salinity measurement, and I feel like that would be a major...

Hi all. I really like the way that red sea have the whole catalogue talking together. Easily controlled in one app, and or controller. Are there alternatives to red sea if you want your skimmer, ATO, return pump and doser to be "smart" together? Only Red sea aquariums are easily avaliable...
