Dosing for coral growth

But my 75g and 150g before that grew stupidly fast, new and once running for years.

Hanna needs something to measure curses -lol

Right, but there are so many variables between tanks.

Age of live rock, how many corals, what type of corals, maintenance schedules, equipment, additives (or not).

Carbon doesn't work at 100% for 30 days then stop. It starts at 100% and gets filled up as fast as conditions dictate.
What happens as the carbon is filling up-the toxins have to go somewhere.

2 equal tanks -
1 with 2 corals, 1 with 50 corals. Both tanks have equal carbon changed at 30 days.

Too soon? too late? Who knows?
