Need ATO recommendation

I have a 215 saltwater reef tank and have been doing water changes by filling up a 55 gallon plastic drum with RO water and manually adding salt in order to do my bi monthly water changes. The problem is that I have 2 of those cheapo float valves. One on the sump to maintain the proper water level, which is to supposed to automatically fill the sump from the drum when needed and one on the drum to assure that the RO water shuts off at the proper level while being filled. Today I'm doing a water change and for whatever reason, the float in the sump is not working properly and does not give me a comfort level. These cheapo float valves continually give me trouble and I'm looking for some recommendations from those much more experienced than I am. Any suggestions would be greatly appreciated. Thanks to all.

 

I would suggest the JBJ ATO system. Its dependable. I have the Hydor ATO currently and it suites my needs but it is a little finicky. It uses temperature to read the levels of water and not mechanical float valves like the JBJ.

I have the avast marine ATO and I really like it. It uses a pressure switch, and if you have the space which it sounds like you do there is an optional float switch which is used as a fail safe to prevent flooding http://www.avastmarine.com/ssc/do/product/rigging/Top-off-Kit

 

Spectrapure UPLC-II for me. Been using it about 7 years now with no issues. It comes with multiple levels of safety for peace of mind too.

 

I've been debating between the JBJ and the one from autotopoff.com. I already have an aqualifter so the price for the later is tempting.

 

If I get an ATO, it will be this one.

You can find video reviews on it on YouTube. Looks sweet.

 

It does look sweet. Has anyone out there used this particular product? One problem I may have is a siphon issue as my drum is situated higher than the water line in my sump.

 

I have the innovative marine aquagadget controller and pump. I love, love, love it. I won it as a prize in the Meme contest. It is awesome, but at almost 300 for the system I think there are other options, not as fancy, that will do the job. But if you have $300 to spend...

 

It comes with a very small, powerful pump.
