That works for me. Not sure my brain has the answers.

For example...I am always always low on ALK...I've been bumping my doser regularly over the last year but still fighting to hit 6 dkh. About 2 weeks ago I changed the head on the doser channel for ALK as the old one had some seepage coming out. Then about a week ago I noticed some strange behavior on a few corals...and it continued to get worse. Had a couple outright die on me. It almost looked like burnt tips and then overall burn on some pieces. Today I retested my ALK twice and I'm at 10.5dkh. Holy Crap!! I had done some recent big water changes and when testing the new Reef Crystals, the ALK was up at 11 but I thought it could only help me since I'm always so low. I didn't think about the fact that the new doser head would function much better and because my doser works on time and speed i was putting a lot more in than before.

Tested my CA which is always high and was down to around 300...so what a mess. Working on some slow corrections now.
