I'll try to keep this brief...
I have a fairly mature system. 180 in the living room was established in 2015. 420 was added in the basement a few years later. All told there is probably about 700 gallons of water. Both tanks are mixed reefs, mostly LPS. I lost a lot of SPS (birds nest, styolophora, etc.) last year following an alk spike.
Both tanks are fairly heavily stocked with tangs, anthias and angels.
In the past few months, the tanks stopped taking Alk and Cal. I am no longer dosing at any two part and my Hanna DKH checker reads at 10 (9 on Trident) and Calcium reads at 530 on Trident, Mag at 1350-ish.
I perform fairly regular water changes, 20-ish gallons per week using Instant Ocean (formerly Reef Crystals, but I am trying to naturally lower Alk). It seems to me that something is inhibiting coral growth, and thus no depletion of major elements.
I attached a Triton ICP test I just performed last week. Thanks in advance for the help.
