I've been off the boards for a few days. Sorry for the late response.

I'm getting 6 weeks out of about 2/3 of a liter in each of two scrubbers ,one on an asm 4x and one on an asm 4xx. Ph pre scrubber was 7.9 to 8.1 range . Now after about 3 weeks ph dips from 8.3/8.4 to 8.2/8.3 as some of the media purples up but it gets a deeper purple in the second 3 weeks and I'm ok with the 8.2/3 it maintains during the second 3 weeks. I think some of the ph boost may be related to the lower relative humidity in the basement at this time of year though.
