    ATO flooding reservoir with saltwater

    Recently turned on a Prism ATO unit with the reservoir being a 5g commercial water container (plastic) after about 15 min after installation I noticed water around the tank. The ATO had some how sucked salt water I to the reservoir and was actively flooding it. Had anyone experienced this issue...

    RedSea ReefATO+ manual scheduling

    Does this have the ability to manually schedule top-offs, possibly in addition to the sensor? This because I'm using Kalk in the top off water. The return chamber on the Reefer 350 is 25x25 cm I believe, and the height between the sensors on the ATO+ is 3 mm, so that's about 200 ml of...

    ATO Improvement

    Hello, I am trying to think of a way to provide another failsafe for my ATO on my tanks and the only idea I could think of is to use a float switch wired inline with the pump wiring. Therefore, if the float switch is activated, the ato pump will not be able to pump water into the tank because...

    Best ATO for Pico Tank

    I’ve finally had it with my current optical sensor ATO. It decided to recalibrate itself a few minutes ago and filled itself all the way up to the high water level sensor instead of its normal low water level sensor. This just dropped my salinity from 35.2 PPT to 34.5 PPT in a matter of minutes…...

    Lengthening tunze osmolator tubing.

    I want to add this ATO to my sump but I don't think the supplied tubing is going to be quite long enough. I need to go roughly 12' and the head height is only about 3'. Do you think I could add roughly 3 more feet to this system without having to use a larger pump?

    Using Topfin Freshwater for ATO ok?

    So I found this at petsmart and is closer than LFS an hour away to get water. I’ve been using to supply my ATO for about a month and I notice a bacterial bloom and possible infection in fish. Is this ok to be using in place of RODI water.

    Optical Sensory ATO frustration

    I got this ATO system off Amazon and it seems like a common enough one with decent reviews (and a lot of the exact same just under different brand names). I have it hooked up from a reservoir to my sump and got the optic sensor to right where I needed it… and then it just fills arbitrarily...

    Red sea desktop (max nano) ATO overfilling tank

    Hello, I've just setup my red sea desktop ATO however i dont think it's working right. I believe the water level in the return pump section of the tank (where the ATO bulb is) is too low causing the ATO to keep filling up the tank too much. The other section of the filtration chamber just fills...
