Best auto top off system?

[Sean minor]

Hi, in the market for a Auto Top Off System, I'm useing float valves hooked stright to my RO/DI and it works great except the RO system stays on and I'm burning through DI filters. Was thinking about the Tunze, need one for a 180 gallon fish tank and 90 reef tank.

any input would be great
Thanks

I have a Tunze ATO and its great. I've also had great luck with a dual float switch from AutoTopOff.com.

I use the Avast pressure switch with a Tom Aquatics aqua lifter pump. I don't know if it's the best as I've never used anything else, but I can say in the 2-3 years I've had it, it's been flawless.

I have used the ATO, the Tunze and currently have the ELOS system. I really like the ELOS because it is not based on floats to keep the water level. The Tunze and the ELOS get my vote for the best value for money/performance.

Tunze for me, for precision and fail safes. You get what you pay for.

I have use the JBJ and the Spectrapure ULPC-II. My vote goes to the Spectrapure model, especially if it will need to pump the water over a good distance

I use the Hydor smart level, and I think it's pretty great...

I have not used anything but the tune osmolator. Zero issues for over a year. Almost forget it's there until fill up time.

Spectrapure UPLC-II. Been bulletproof for over 6 years for me. More compact than the Tunze and much more user adjustable with multiple levels of safety. Those who have tried it swear by it and would never go back to anything else.

Tunze Nano works great!

Tunze Nano works great!

Is there a tank size limit for the Tunze Nano? What's the difference between the nano and the regular?

You know, I think I'm gonna stick with the old system of a old school Kent float valve in each sump running straight off the RO unit, been working for 25+ years, I think I just got caught up in all the new high tech toys, LED lights, and bad *** pumps and it went to my head. But thank's for all the input.

Thats what I use but both tanks use a lot of water and it is always running, been leaving the pump off so not to mess it up from cutting on and off, only use it to make mixing water.
