I set up my brand new DOS according to the instructions.
I calibrated it.
I went to BRS for the recommended dose to get my ALK from 7.6 to 8.5. For my tank (220 gallons) it said I needed to dose 140ml of their BRS alkalinity solution.
I set the DOS to run for about eight hours and to deliver 120mL. I checked the interval summary and it said that it was going to deliver about 4mL every ten minutes.
About 30 minutes later I checked the log and it says it did two doses of 200mL each time. More than DOUBLE the TOTAL it was supposed to deliver. If I hadn't checked I assume it would have emptied the whole bottle and my Alkalinity would be about 25 dKH. As it is, my Alkalinity is 11.4.
Has anyone else seen this type issue? I am now very leery of trusting the DOS.
I am doing a water change to hopefully get my ALK down.
Comments, opinions, guidance appreciated.
