Need help deciding auto top off

[willforr]

I’m in the market to buy an auto top off system. The problem is I have an all in one tank and most of what I’ve seen are designed for people with sumps. Does anyone have an idea for what I could buy that would work for me? Please let me know, thanks

Use a Tunze 3155 with ato reservoir on a Red Sea Max C-130 — works perfectly!

I use a tunze 3155 for my 20 gallon IM fusion and have the sensor in the back chamber. It’s a tight fit but it does and then have the pump in a separate 7 gallon jug to the side of the tank. Ive had it for a year and a half on there and no issues. Just have to fill the reservoir every month or so.

Just about any ATO will work in an AIO. Duetto, ReefBreeders, any with an optical sensor.

Big fan of Tunze ato's

Love the Duetto. Is working perfectly on two separate tanks.

I also have a Tunze 3155 on my IM Fusion AIO 30l. I also slowed the periodic top off amount, because the 30l is a small tank for the 3155.
