RTN prevention in Acropora

Dead spots are the worst. I added a tiny powerhead in the back corner, and my Acros perked up. Also, hype, you dipping new frags? Some pests sneak in and stress 'em out.

Second the dipping. Bayer's a lifesaver. Hype, you got any pics of the RTN? Sometimes the pattern clues you in.

Pics would help. Also, how's your calcium? If it's too high, it can bind up other elements. Aim for 420–440 ppm. And don't forget to test at the same time daily—params fluctuate.

Consistency's key. Hype, keep a log if you aren't already. Track params, changes, and coral behavior. Oh, and what's your tank's age? Newer systems are more prone to instability.

Tank's 9 months old. No new fish, and I dip frags in Revive. Flow's two MP40s at 60%. I'll test magnesium and phosphates tonight. Appreciate all the advice!
