any advice on my water tests?

[tara_karan]

Here are the latest tests on my 90 gallon which has been going since June 17th:
temp: 77 F
Sp Gravity: 1.023 almost 1.024
pH= 8.0 (have had a terrible time raising it, never has been lower than this though since day #1 with no livestock at all)
KH= 9
NO2= <0.3 mg/L
NO3= 0 ppm
Calcium 360 ppm (adding purple up to try to raise it)
NH3= 0 mg/l

Using salifert and tetra test kits. Checking tests weekly at this point. All livestock okay. Need advice on raising pH!!!!!!!!!!!!!!! Current livestock are blackcap basslet, pygmy angel, 3 green chromis, 2 clowns, mushroom coral, peppermint shrimps, conches, snails (nassarius, cerith and astrea), emerald crabs and some scarlet hermits. Obviously not getting any corals or anything for awhile (am considering a feather duster)
