Hello, I had the tunze osmolator and it was ok, except the little pump was too loud for a quiet room and when calcium built up on the sensor it would malfunction. Is there a quieter and more reliable top-off than the osmolator? thanks
I have reef fanatic and it works well for me, but I must say the controller stuck into on position once and dumped the whole ATO container into the sump. It happened only once but it happened I like the fact that tunze use magnets for their sensors. I also have ATO from autotopoff in my FW tank and no complains so far. Little bulky, but it has the snail protection
I have 2 tunze units and have never had a problem been operating for over 2 years. I also had a unit from autotopoff.com as well on my first system and that worked flawlessly as well.
Ive had tunze and works great never fails. And double switch From auto top off.com is great also with aqua lifter pump. both Been in use for about 3 years
