Any work being done on an auto top-off?

Maybe this will give you some ideas.
The RO/DI unit is under the sink. I have the feed line to the unit plumbed through a Reef-Relief system. The water from the unit goes into an old salt bucket for storage. The Reef-Relief will shut off the water if either float switch in the bucket is activated (open) and if there is a power failure. I use the AC III Pro to turn on the Reef-relief for an hour. This is long enough to fill the bucket. This way if there is a leak in the RO system then it would be limited.
I have two ways to feed the sump, either directly from the RO/DI bucket or through a kalk reactor. The kalk reactor is feed using an Aqua Medic SP 3000. This is setup so that until my Ca demand increases I can still maintain constant level in the sump. Also if the pH rises too high the kalk pump will be shut off but the sump level can still be maintained by the fresh water powerhead. There may come a point in time that all the top off will go through the kalk reactor. However, this will be easy to program in the AC.
I use a AC III Pro to run the system. Some things it does:
Turns on the kalk dosing pump at night. I will control the time period depending upon Ca demand.
If float switch 2 (hi level) is activated the power to the power head, the kalk dosing pump and the reef-relief are turned off.
If float switch 1 is activated, which means the water in the sump is at the correct level, the power to the power head and the kalk dosing pump are turned off.
If the ph rises above 8.4 the kalk dosing pump is turned off.
It turns on the kalk mixing pump (not shown) four times a day for several minutes.
