I use nopox to keep the phosphate and nitrate low. I only dose about 2ml daily.
I did a 30% water change over the weekend and the carbon in the internal and external is less than 10 days old.
Nopox has been used for over 18 months now..the zoa problem is 4 weeks old. 2 hours ago all the colonies were wide open. Now they are about 75% shut. There is one ( a pink centred zoa ) that is still fully open.
Makes no sense.
