I got my Apex with DOS yesterday. I have it mostly set up now.
I have a few (probably easy) questions for more experienced people out there.
I want to dose BRS two part into my basement sump. My display tank and sump total about 220 gallons.
My Alkalinity is currently at 7.6 dkH. My calcium is at 380 ppm.
According to the BRS calculator I need to use 140mL of their alkalinity solution and 901mL of their calcium solution to raise my values to 8.5 dkH and 420 ppm respectively. I am new to dosing so before I kill something I wanted to make sure these numbers pass the "reasonable-ness" test. Comments appreciated.
So now on to the DOS questions:
1) The DOS appears to work on a 24 hour schedule. I set up pump one (alkalinity) to run from 0700 to 1200. I set pump two (calcium) to run from 1200 to 2359. Does this sound about right?
2) Since I think the amounts are fairly large will the DOS try to do the entire amount in one interval or will it do some portion on day 1 and do more on day 2 etc.?
3) I assume that the intervals I set up in Apex run every day moving forward through time, right? So I will need to modify this set-up once I get my values up to the desired values so that the dosing amount holds them steady, right?
4) When I create an interval of say 1200 to 2359, and the current time is say 1400, will the DOS start immediately or does it wait until the next scheduled interval to start?
5. When I was calibrating the pumps I had to prime them. Now that they are set up, do I prime them? I assume that once primed they will hold their prime, right?
Thanks in advance for any thoughts, opinions and guidance.
