I guess dosers on timers were not ment for me. Should have bought a all in one. First time I forgot to set a off time on one of the times and ran mag for at least 12 hours which wasn't that big of a deal. Second time I was low on alk so turned it on for a few minutes and ended up leaving 7 hours later I was out and about and it hit me that it was still running alk of 18 when I got home. Last night I upped my dosing time for vinegar I know for sure I made sure it was on auto but some how it was on. I came home saw my tank cloudy thought maybe I added to much of a bump in vinegar. Figured I would make sure anyways the doser was on all night the only reason it stopped was it emptied about a quart of it. Just did about 30 gallon water change hoping everything turns out okay. These dosers are gonna destroy my tank at dome point.
