I have a tank that is close to 2 years old. Back in October I started the switch to the Triton method. Things seems on point and results some back decent. I'm dosing 20ML of Elementz, all 4 parts, per day.

Calcium 442
Mag 1402
Phosporus 22.47
Phosphate 0.068
Alk 149ppm

Working on the adjustments and trying to keep things inline. I had my GFO reactor off but have since turned it back on (about a week ago).

Corals open, fish are happy, nothing on sand. Just on rocks.

I had my MP40's turned down (30%) and have moved them to 40%. I also moved one more in the center of the tank, as I was thinking I didn't have enough flow over the tank (done today).

This stuff comes right off if you pull it .. it isn't hard or sits straight up.

Attached is a pic.

Any help is appreciated.
