I want to dose Kalc using an aqualifter pump via a K1 kal reactor.
I want to start slow and only dose @ 0.25 gallon a night only.

the Aqualifter has a capacity of 3.5 g per hour
so thats 219.55 ml per min
.25 gallons = 946.35 ml

946.35ml over the course of 12 hours = 78.86ml once an hour for 12 hours

so if i wanted this to start at 10pm and end at 10am what would the code look like?

Use the oscillate statement to get your on/off times once you figure out how many seconds per hour. For example, 20 seconds per hour would look like

OSC 0/0:20/59:40 Then ON

Then, turn the outlet OFF the times you don't want it to run

If Time 10:00 to 22:00 Then OFF

That's the basic gist of it. Give that a try.

Do a volume test on that AquaLifter.... put the output into a empty container, run it for exactly 6 minutes, measure the amount pumped, then multiply by 10 to get the hourly rate. I had three, and each pumped different amounts in the same period of time. None actually pumped the rated 3.5gal/hour amount; all pumped less, one was just over 2g/hour.

Thanks I finally got around to setting everything up tonight
Im going with on for 2 minutes once an hour for 10 hours
im finding that the aqualifter or the K1 kalk stirrer is taking about a min to start after power is sent to the aqualifter...so im figuring 1 min dry and then 1 min of kalk......heres the code im going to test out...hows it looking?

Fallback OFF
OSC 000:00/002:00/058:00 Then ON
If Time 12:00 to 23:00 Then OFF
If pH > 08.25 Then OFF

Great advice!....i found that after adding a check valve and positing all my tubing, my aqualifter is only putting out @600 ml every 6 min so thats @ 1.5 gallons an hour. i also found it takes about 1min to kick in

changed up the times a bit

Fallback OFF
OSC 000:00/002:00/058:00 Then ON
If Time 10:00 to 22:00 Then OFF
If pH > 08.25 Then OFF

now if i want it to activate the last 2 min of the hour would i just reverse the command?
OSC 058:00/002:00/000:00 Then OFF? does that seem right?
