Need help with Dosing

[Jewel]

I've got 2 BRS Dosers and I want to set them up to pump 30 ml per day or night, They say they'll pump 1.1 ml per minute, Is that exact for all of them? If so that would be on for 27 minutes then off for one, Then the other the same but start it 10 minutes after the first one has ended, Does that sound about right?

on for 27 minutes should give you 30ml like you said.. you can test it by simply running the dosing pump into a measuring cup for 27 minutes to make sure its good to go and you get the amount your looking for.

I personally wouldn't run a BRS doser for half an hour straight, you could have quite a PH spike depending on your water volume.

Really! Ok then 10 minutes 3 times a night. My tank volume is 75 GL total water . How does that sound?

Should be fine, just allowing it to circulate, then keep checking your levels for the next month almost daily.

I think it's best to do lots of little doses, especially alk because it helps prevent solidifying in the lines, I think I ran my program as 3 min on, 30 min off with 20 reps to get about 70 ml a day. I ran alk at night and ca during the day.
Don't worry so much about exact numbers, set your program and test frequently and adjust to get the results you want.

Sounds good, I'll try that.
