Yea..I wish there was a pump like my osmolator pump that runs on an outlet..so I can hook it up to my APEX to keep the level up. I'll have to find a small pump that is good at this. Something like the osmolator pump would be perfect.
I am using my Apex to do all the Kalk dosing functions. Here is what it does:
>Doses kalk to tank via 50ml/min BRS doser for 3min 20sec 4 times per hour using the OSC command
>Stirs kalk via a pump for one minute every hour
>Turns RO/DI on to fill reservoir 4 times per day for 20 minutes each time (dosing is skipped once during this since the stir pump also comes on for the last 10 of the 20 minutes)
>Shuts down kalk dosing if pH gets to a certain point (right now I have it set at 8.6)
The higher output BRS doser is more than enough to put plenty of kalk into the tank. This schedule keeps my tank topped off almost perfectly and is easily adjustable. The reservoir is a DIY unit using a 6.5g salt type bucket. I dump a few cups of kalk in wheneve the pH seems to be lowering. I will say that I am unable to get my pH over 8.4-8.5 without spiking alk to over 10 which I do not like to that high. I also dose 2-part using BRS 1.1ml/min dosers but have not had the alk doser on for quite awhile and the calc doser runs for 20% of what it use too when I ran them both.
This system has been very stable and mostly foolproof although the 50ml BRS doser just quit on me (BRS says that is rare and that I in no way overworked it) and they are out of them. I rigged up a aqua-lifter to get by and for comparisons sake I have it running for 20 seconds 4 times an hour instead of 3min/20sec. It is not as accurate as the BRS doser but close enough.
If you would like more info or some pics of the reservoir/setup I would be happy to do so. One thing I do have as a worry is that if the Apex freaked out and kept it turned on I would be in trouble. I really do not see that happening - not anymore chance then something going wrong with any other system really.
