Your calcium is low for rapid growth, 410-450 would be better
Calcium and alk need to be constantly in the upper ranges for good coralline growth. If the growth you get is not good enough for you try testing your iodine.
Iodine:Use aquarium products only when adding iodine not all iodine is the same some forms are toxic. One more note on iodine it changes form in the aquarium and test don’t identify all forms so always add half recommended dose. Now that sad if you do regular water changes you may test at good levels for all elements and not need supplementation. I use Kent Marine and if you start to see green algae growth cut back on iodine dose.
Purple UP I tried it but I like dosing calcium separate gives me more control...
