Another dosing question

vanzea · 03/13/2012, 04:06 PM

I set up my two brs dosers. I will be dosing calcium and alk. one question that i have is i have read i should not dose near my return pump. given my set up this seems to be the best spot in my sump to do so. The dosers are 1.1ml a minute---will this be slow enouph of a dose that I can dose here?

anyone have an idea?

How big is the water volume into which you're dosing, how much flow does it get, and are you using the high-pH formula (recipe 1)? I'd probably dose into the display rather than into a return pump area.

water volume is about 5 gallons. My return pump is at about 950gph. Yes recipe 1

anyone have trouble with this...Im thinking that 1.1 ml is a slow enouph dose to not effect the pump...is this correct

Hmm, that seems reasonable to me to try, but is the return pump rated at 950 gph for the head loss of your system?

I'd check the insides of the pump now and then, just to be sure.

its rated at 1150 with the loss im getting about 950

Okay, I think that sounds like a reasonable setup to try.
