What’s the secret to growing SPS and producing good color? I have 60g w/ 7 fish Lighting AP700 Ammonia 0 Nitrite 0 Nitrate 20 Ca 420 Alk 9.2 Growth on my one sps, monti and birds nest is slow. I have them in medium to high flow area. Feed fish once a day. Any suggestions from reefers who grow sps without any issues is appreciated.
