I finally bought some new equipment for my tank, so its been upgraded from my super low-tech set-up.
I got a 5 stage RO/DI system and a JBJ ATO system from Bulk Reef Supply. Here are a few photos of the new equipment after I got it set-up and installed.
Here's the inside of the stand with the ATO FW reservoir and Aqualifter pump.
The float switch in the back right corner of the display tank.
The other float switch in the FW reservoir.
The JBJ ATO controller mounted on the wall behind the tank. I can see it and get to it from the side of the tank, but if you're looking at the tank from the front, its out of sight. Its stuck to the wall with the command strips that are like velcro, so I can pull it off to mess with it and then pop it back in place.
Underneath my kitchen sink. The orange bucket is my storage container for the RO/DI water and then the RO/DI unit is back behind it.
The RO/DI system.
The float switch inside my storage bucket so that the RO/DI will shut off automatically when it is full and not overflow the bucket.
How the plumbing is set up. The black angle stop adapter is plumbed into the cold water for the kitchen faucet and reroutes some of the water to the RO/DI system. The ball valve installed below that on the red tubing is to turn on and off the water flow to the RO/DI system.
