why can't the answer be the simple fact that your acros (and everything else) started growing faster than before and therefore consumed more alk and ca? I know nothing about AcroPower other than what I just read. And the advertisements/reviews say it is supposed to increase growth/color etc.
For what its worth, I don't think 40 ml of CA and 35 ml of alk is a lot. I have 12 small frags of acros and I am dosing 190 ml of Randy's 2 part recipe B. I have had my doser for a couple months now and feel that I finally have it dialed in. To get it where you want, I would test every day at the same time of day (very important). After each test, I would use the calculator to find how much 2 part i need to get it to that exact point I want. I would manually dose that amount (regardless if it was 1-3 dkh). Then I would take that amount and add that to my doser settings. After 3-4 days you should have it dialed in to within 2-3ml. Honestly, it has taken me forever to dial it in and I feel I only got a handle on it once I started checking at the exact same time of day. If you break it down by the hour, my tank is consuming 7.9 ml per hour, so testing at 7 instead of 9 means I would be off by 15.8 ml. Crazy right...
As you know, CA and alk are consumed in almost equal parts. If you are experiencing differences, then I would strongly suspect that the ingredients to make the 2 part were not consistent (done that), hence the variation...or that your doser lost calibration (done that)...or the doser was sucking air because the tube wasn't down far enough (done that)...or the kalk topoff stopped working and disrupted input (done that).
Please post how you solved this problem when you figure it out...
