@Cliff - I have a calc reactor dosing magnesium (dolomite), calcium & alk. I give them a boost when I need to w/ epsom salt & calcium chloride. I use intant ocean salt and dose trace elements weekly (if I remember).
For a while there I was adding an elos phyto product (which was dried phyto) w/ a .4 (the big end of the black scooper from elos test kits) scoop daily in the am before work when the lights were off.
