Dosing pump for AFR

[RobertK]

I'm thinking of switching from 2-part to AFR. My dosing pump is an old Spectrapure LiterMeter 3. It still works fine but only adjusts in 10 ml/day increments. The dosing calculator on the Tropic Marin website suggests that for my 60 gallon system I use starting dose of 11.36 ml/day, and maximum dose of 56.78 ml/day. With my dosing pump I'd only be able to dose 10, 20, 30 ml/day, etc. Do I need to get a different dosing pump for use with AFR? Does your dosing pump allow smaller increments of adjustment? Thanks!

My ocd only allows me to dose in 10ml increments anyways lol.. I have a Neptune dos that can dose at any Increment but I don’t lol.. I think you’ll be fine..

I use a reefdose and love it but RS doesn't offer a single head. I've used kamoer f1 and x1 also and they worked fine.
I'll just throw this out there but since AFR takes a while to actually work its magic manually dosing is fine and what I did for months. I only moved to a doser because I was forgetting. I have my doser dump the whole daily dose in one shot and the tanks does fine. I think @Randy Holmes-Farley uses a single dose IIRC

OK thanks Troylee. Guess I'll start at 10 ml/day then and increase as needed to get Ca and alk in range.

Thanks exnisstech, will have a look at the reefdose if my Litermeter doesn't do the job. I don't use a Neptune so need an independent dosing pump.

I use the redsea 2 head doser. One head doses AFR and the second head doses Elimi-NP diluted in AFR (1 to 4 dilution). If my phosphate ever stabilizes I will switch from diluted Elimi to diluted NP-Bacto. If you are interested in carbon dosing this may be a solution.

I use the BRS 1.1 mL per min doser on a timer for AFR. :)

Hey Randy by chance what brand do you use for the timer for the BRS doser I was considering adding AFR dosing but I really wanted to get a reliable brand as I was afraid of it turning on or off.

I use these for AFR, AWC, ammonia dosing, phyto dosing, phyto stirring before dosing, and refugium lighting. :)
