i'm noticing my alk is rising. searching previous threads i've come to realize it could be:
test error
sand/rock dissolving
no3 lowering
i am testing alk with hanna checker and red sea test kit. ranges are close, but not exact. so i am ruling out test error.
how much no3 decline warrants a raise in alk?
