40g cube ATO recomendations ?

[TMallan]

GM All, looking to install an ATO on my 40 gal reef tank and hoping someone can tell me good things about theirs? I would like to be able to pump from a 5 gal water jug ( Poland springs or the like)

TIA,
Tom

Ive had nothing but good experiences with the XP aqua duetto.

If you want to spend more money on something, get the spectrapure litermeter.

A lot of reefers like the Tunze Osmolators. The older 3155 I think was their best, but the newer Osmolator 3 is also well liked.
