ato or no ato

[mark]

After now having one can't see now going without.

I'm just using a humidifier float valve from HD, mounted on a bracket attached diagonally in the corner of the sump so I wouldn't have to drill the side.

Though I'm using the float valve connected directly to my ro/di (no TDS creep btw) it could just as easily be hooked up to a storage container above the sump.

after reading these posts I think I've got to get a ato unit instead of manually doing it. For some reason I always thought it would be more complicated to set up.

If you build or buy be very carefull. There are lots of horror stories on nano-reef.com where ATO have killed the tanks.

A good one is invaluable I'm sure but if not built correctly a turbo snail can kill your reef.

Osmolater is the way to go...
If it runs for more than 5 minutes it shuts down. There's also a high water level alarm built in.

I use a cheap gravity fed pond float, Kent makes one and I think similar is available from other places, it goes in your sump and total cost was under $30. I've been using the same one for years.

As other people have said the osmolator is great. I picked one up a couple weeks ago and love it. As mentioned all you have to do is mount the optical sensor inside your sump at the height you want your water level. As soon as your level drops below the sensor it will turn the pump on and top up for you. This system is not for use directly with your ro/di. You need to have a reservoir full of top up water and the pump is placed in there. Currently I fill up my reservoir weekly, much better than having to top up daily. HTH
