Why is my Acropora not branching?

Thanks for all the suggestions, everyone. I'll check my alk stability and maybe tweak the flow. Running two Nero 5s right now, but might add another. Also gonna test phosphates and look into trace elements. Appreciate the help!

Glad to help! Keep us posted. Oh, and if you're adding flow, start slow. Too much too fast can stress them out.

One more thing, SilverAce. How's your coral placement? Acropora need to be high up, close to the light. If they're too low, they might not get enough intensity to branch.
