Can you show us the distance between the gyre and the frag and what % is it running? I'm thinking about getting an additional pump ( It is kinda overkill but my rock layout is scuffed so I can't get high flow everywhere) and I'm afraid it might be too close . Also thinking of dropping KH to something around 8 ( this will take a long time), Very nice looking colony , those coloursSpaths absolutely love getting crushed with par and flow in my experience. And I mean crushed. I've had a few over the years and currently have grown out this beauty that I have way up high under a radium and in front of a gyre.
