Thanks m8
Yes it's a real challenge to manage flow with colony's this large and this coral density.
A consumption of 4,85 dkh per day is absurd high.
Imagine what would happen if you stop dosing.
The Alk would drop more than 4 dhk per day
Flow is limited by the coral mass, so cyano is always lurking.
I use a CP55, OW8 and a tunze ejet 3005 for flow.
To optimize on flow i have them on timeintervals
I use this as a base :
