I thought I had everything under control. I got my levels back to where they are supposed to be. The heavily damaged corals died but some only have brown tips now. Today I noticed another piece starting to lose flesh. Does this look familiar to anyone? My alk is 2.0 meq, which is low and calcium is 340. My alk keeps dipping low. I thought my calcium reactor was supposed to help with my levels but the stupid thing doesn't ever keep a steady drip. When I get the drip level where I want it the next day it comes to a complete stop. Could it be pressure related or is it just a bad diy design.

The first tee goes to the reactor, nothing, and phosban reactor. The phosban is the last in line and it seems to flow at a constant rate.
