I have a 75 gallon display in a basement, so fairly cool surroundings but a little higher relative humidity. I think ATO is currently less than 1 gal/day but haven’t been monitoring that closely as osmolator keeps things topped off and I have a large RODI reservoir on which I push a button every few days to auto-refill. I’d like to switch from tunze ATO to doser for a couple of reasons:
1) To facilitate sending some of the ATO water through a kalk stirrer. This is the primary motivation.
2) To be able to monitor and learn more about losses so I know how long the reservoir will last, etc.
3) To make it easier to pause ATO for various tasks. I know I could do this by putting the osmolator on a switched outlet, but every time it is power cycled it runs for about 15 seconds.
Now for the questions:
1) Can doser 2 manage ATO of up to about 1 gpd without too much stress on the motor?
2) Searching I have found a few different ways people have tried to control send ATO through kalk or not (I don’t have KHD at this point) but is there a preferred way? I was thinking of just trying to find a max volume of kalk each day and when that is exhausted falling back on straight RODI.
3) The return chamber of my sump is not so large (12.5x5 inches). Is a single float valve sufficient to run the ATO (with probably a second high water float as an emergency backup)? Would you put a delay on it to prevent it running very often or is frequent small dosing desired? I just don’t want to burn the motors.
4) Are optical sensors significantly better for this purpose than floats? I already have the floats but could add optical if really necessary.
5) Only tangentially related, can a float valve live submerged as a low water alarm that shuts down the return and, if so, does that significantly shorten its lifespan?
Sorry for all the questions (and I am sure there will be more as I try to implement other tank tasks). I am trying to search through what’s already available.
