Tunze all the way... I just replaced the pump on mine, as it was about 5 years old and finally gave out. But the replacement was only $30. Great and reliable.

Yeah don't want to derail but I think the consensus here has been reached and we all know Mike is one hell of a lucky SOB =)

Basically my unit was new and when I filled my tank up I accidentally submerged the entire control unit! So I unscrewed it and 'washed' it in a bucket of ro/di and allowed to dry. That's the only reason I opened mine up I've never had any other issues.

The main reason float's fail on people is because of salt or algae build up on the seal. They only use the weight of the hanging float to seal, so it doesn't take much. Make sure it's somewhere that never see's splash, or always see's splash and gets flushed, and everything should be fine.

Greg I appreciate what you're saying but a consensus was reached man =)

I'm also leaning heavily towards Tunze ATO, but out of curiosity, has anyone seen or used the "Storm" ATO system from Genesis Reef Systems? It looks like a nicely equipped unit for about the same price as the Tunze. The "Renew" auto-water-change system also looks pretty cool.

Damn it anyway, no one listens to me any more :sad:

I did not realize that you can get a Tunze complete with a pump, when I first look at them some time ago I didn't see a pump with them.

Scroll up =) Post #10...

I just use a simple 2 float system from my rodi. If the first one would fail for any reason, the 2nd one would stop the flow 1/2 inch higher. Seems pretty fool proof to me.

Was Greg here? Just wondering as I thought I heard him.... HEHE :biggrin:

Another thing to note, is that I have my water line for the Tunze setup so it is actually pouring the water over the IR sensor and float switch... I have never had to clean either in all the years I have had this, they stay clean because of this. FYI...
