To the top.

Try autotopoff.com. Way cheaper then the Tunze and pretty much ready to go (you have to supply a pump for the water; an aqualifter works well for that.)

I've used jbj, kent floats and tunze osmolator.
Tunze has the best ato system out of those three.
Bullet proof.

Ya, I have tossed around the idea of a DIY, or one of the cheaper float types, but I think the Tunze's really win the gold in this case. Salinity is pretty important.

important enough to bite the bullet and pay FULL PRICE :laluot_20:
?

I'm getting close, but I buy all my equipment used. There is no piece of hardware on my tank that I bought new.

Bump.

Thanks!!!
