Our Red Sea 425XL has been up for about 18 months now after a restart, its an LPS tank (except one Kenya tree and a couple zowa). Since we started we have never had any Alk, Cal and Mag usage, everything looks happy but nothing grows.
I have just done tests and they are almost identical to 5 days ago
10th July
Alk - 153 (8.554 dKH)
Mag - 1440
Cal - 440
Nitrate - 15.7
Phosphate - 0.09
Today
Alk - 152 (8.498 dKH)
Mag - 1440
Cal - 440
Nitrate - 16.9
Phosphate - 0.08
I also have no Coralline algae in the tank, the only things I am dosing are Phosphate and Tropic Marin Pro Coral A & K
Does anyone have any idea what could be going on?
Thanks
