I try to maintain 7. thats neautral. some people prefer higher numbers everyone is different .thats the main difference in sps vs.mixed reef tank or softie tank .(well that and phosphates, lps need some phosphates to keep their color while sps need super low phos to get fully colored ) I read that the germans keep reef tanks 7dkh . and those guys know how to do everything ...lol...i wouldnt let it get any lower . that will effect the rate the calcium is being consumed . my experience high calcium and low alk maintained would make sps coral grow fast and thin , like caps and chalice etc. keeping alk at 7+ made the coral grow slower and thicker .the lps like the lower alk numbers . once i went from 6dkh to 9 to help with girth all my zoas and lps were very unhappy . thats how i got my reef to grow so fast anyway . just my opinion . keep it a secret though . i dont want anyone knowing my tricks .
