I have found that cal 440 mag 1300 and alk 9 is the sweet spot for growth. I also find if your nutrients are low which they will be soon with the np bio pellets, sps really need amino acids or some kind of feeding like coral frenzy or something with a very small particle size. I would love to see some before and after pics. i here great things about the np's bp. I personally does vinegar supersaturated with kalk but i have been thinking about switching to bio pelltes once i get a nice reactor to run them in.
