Who Gives A Fish Forums

Thanks for the tips, everyone. I'll try target feeding and check my nitrate levels. My calcium is at 420 ppm, and I do weekly 10% water changes. Flow is moderate, so I'll keep an eye on that too.

My Blastomussa has been in the tank for three months and hasn't shown much growth. It's under moderate lighting, 75-gallon tank, with stable parameters: 78°F, 1.025 salinity, 8 dKH. Anyone else experience slow growth with these corals?
