Running out of space in my return section so looking for other possible locations to drip my kalkwasser/lime water. I was wondering if I could put a tee fitting in one of my drains for my remote/display refugium and drip kalk straight into it? From there it would flow down the drain into the first chamber of my sump. In that compartment of the sump the split drain dumps along with the secondary and emergency. I’m planning on growing chaeto also in this first chamber. Wasn’t sure if this would have any ill effects on the chaeto or any other issues?
