Hey bigpow, thanks for the link.
I did a little researching and found that SRI's sand is river sand, and should contain no seashells. RMC's sand is from Monterey Bay, so it contains a small amount of shells. Shouldn't be a big problem, though. I have RMC gravel in my swordtail tank now, and the pH is around 7.2-7.5, perfect for swordtails.
I would like to try SRI's product on my next tank. Is it available in the Bay Area?
