Looking for a basic ato package fire my 55

[Jl330]

I'm over trying to manually do this with RO water.

What's a good basic all in one package for a sumpless 55? I can run a line to a 5 gallon bucket as a reservoir in the cabinet next to my tank.

The gold standard for ATOs is the Tunze Osmolator. However, this might be too obtrusive for a sumpless tank.
Some other options are:
AutoAqua smart ato
Aqua Gadget Hydrofill

 

[Jl330]

The aqua gadget doesn't come with a pump does it?

 

[Pivitol]

+1 for the Tunze

No, it doesn't.
