my tap water is a pH of 7.3. I figured with the crushed coral should bump it closer to 8.0 but hoping for at least 7.6-7.7. Hoping this will add hardness to the water as well, currently tap water is kH of 4 and a gH of 5. I'll run the filters with the crushed coral for a week or so, see what my numbers are. If I can't get them up, then I'll go with the arganate sand /pool sand mixture.

Hey Cj, you don't need 8.0 ph right off the bat. The fish you buy are probably not going to be in ph that high. Our Haps/Peacocks are at 7.8 ph and the Tangs at 8.1 but Tangs have different requirements than Lake Malawi fish. Pet stores do not buffer their water (at least none I know of do) so unless you buy your fish from someone's tank who can verify the water parameters you are better off to increase your ph gradually after you have your fish settled in for a week or so.
