I had my Mg up a bit, but after a week long vacation things are back down???? I didn't add any Ca or Alk suppliment the whole time I was gone and I did put MgCl & MgSO4 in the top off drip line water.
Bertoni: if you are still following, What is that DIY suppliment recipe exactly that I would have to add 7 liters of? What amount of MgCl & MgSO4 are we talking per liter. I have added what seems like a lot to me and I am back to square one somehow? The system is at least 250 gallons of water, likely 275.
I will be adding another 100 gallons to the system soon.... is there a good salt mix out there with high Mg levels that I can use to help boost the levels?
