Auto top off

[Mike Mann]

so i need an ATO and im trying to figure out which is better so i want your votes on which i should choose!:

 

 

Tunze 3155 Osmolator Universal (Auto Top Off) *NEW* w / magnet

 

or

 

Avast Marine works auto top off

Avast. Love mine. Easy and simple to setup and use.

I like the ones with the tubular pressure switches... no moving parts subjected to the harsh environment in the sump.

 

The only ones I know of that do it are the AVAST and litermeter model (which really are not comparable in term of features and hence cost).

[epleeds]

You could use both. Get the avast and then pump the Tunze pump seperate since the avast needs an additional pump

[Ryan S]

Avast. I prefer the pressure switch as well.

[Mando77]

Avast because of ease of use, price and flexibility. I have 3 of them.

[bravanc]

Tsunami makes one that I have been using for years. I also have the avast too. Both are the tubular style utilizing the pressure type switch

[overklok]

Tunze makes the best. Optical reader, no moving parts to get jammed.

[ErikS]

Really comes down to your needs. Avast is cheaper but requires a pump, depending on configuration may bring the price closer. It also has a 1/4" swing each way (1/2" total).....may affect you, may not. Tunze is expensive bue has proven reliable.

 

I would say both are better than float switch models, though I did have an "industrial" DIY that worked flawlessly for 5 or 6 years.
