i have only seen the pinholes in the ciliata. i dose kno3 every 2-3 days, flourish twice a week, and leafzone once a week. i have the morton salt substitute, but i am unclear on how much to dose. i read the thread on it, but im still not sure. also would the phosphate in it raise po4 levels any? if someone would give me some advice on dosing it, i would greatly appreciate it.
