I manually dose my reef tanks on a daily to weekly basis, for my alk I use gravity fed drip dosers and re-up them every other day or so, and for everything else I dose weekly. I used to have an automatic doser but unfortunately it malfunctioned and dumped a bunch of magnesium in my tank causing a big coral crash that took a long time to recover from. I lost a lot of my favorite corals from that so ever since then I've been wary about using a automatic doser again. Has anybody else experience something like this? And do you have a preference for manual vs automatic dosing?
