@Randy Holmes-Farley any issue dosing these two around the same time? I am currently using one dosing pump to dose a combined mixture of vinegar/vodka 2x/day. I just set up a second dosing pump to dose H202 30 minutes after (2x/day) the vinegar/vodka is dosed. Does this sound reasonable is there any issue with these being dosed around the same time? Thanks in advance!
