That's what I have... in operation... & I'm still having to increase those dose's weekly. Every time I test which is 1-2 times weekly, I use the BRS calculator, top up & increase the dose to accommodate what has been used in the previous 24 hrs. let it go usually 3-4 days check & it'll be low. So then I'll top it up & repeat, top it up & repeat. The reason I got a doser was so that I didn't have to try to maintain by means of testing so frequently..... I can't have a reactor on this setup. I've had this online since Jan. & the daily amounts have been increased every single week with the exception of one. If that's set it & forget it, then I must be missing something because I've yet to achieve & maintain levels yet. My corals are growing & thirsty?? but this is high maintenance.
