This is something new, and another new problem for me guys; it's that time again :thumbsup:

OK, in the three years doing this not once has my ph in my res DROPPED.

What could it be? What's new??

I've been adding CAL-MAX (like calmag plus)

I added it last Saturday and changed my res Wednesday. The ph didn't go down on Wednesday from the previous adding on Saturday.

Now 3 days later, today; my ph went down from 5.5 (Wednesday) to 4.6 (today)


What's going on guys?
