Ok, what's the secret?

I never seen a lot of growth in mine till I put it a bit lower and out of the direct flow I'm not sure what it liked more less light or less flow but after that in like 2 months it doubled and a bit

I've had mine all over the tank, no difference. I currently have some orange that is just an encrusted base with some nubs. No growth. My caps and encrusting pieces grow well, just the digi sucks

Your not the only one Brad, I was just over at Ryan's for a few pops and a few more frags and I was saying how out of all the common sps frags I have acquired, my orange branching digi is the only piece in my new reef that hasn't grown or even encrusted at the base for that matter

Try peeing in the sump just after the skimmer. This should raise you PO4 and nitrates sufficently to grow digi's. Just regular old fashioned ****.

Make sure that you have not been drinking vodka cause any residual ethanol may cause a bacterial bloom and be counter productive
