For 8 months this tank was using a jabeo or how ever you spell it 4 channel doser. Grabbed a used one for $40 bucks and it worked just fine. Calibrated the thing once a month. I hear slot of mixed reviews but it did just fine for my tank. Isn’t silent but isn’t loud compared to some equipment I’ve heard. I just set it to dose 12 times a day “x” amount of alk divided by 12. Noticed my corals consumed more from mid day to about 8pm and slowed down. So I adjusted my dosing for that as well. Took time to dial it in but once it was it was great.
I now use the dos to dos alk and nitrate and the jabeo for Red Sea colors and calcium
