I'm not digging the Oceanic, I switched to it from Pacific Coast, and I'm going to switch back. The high calcium is great, but the low ph sucks pig butt. Even with buffer, I can't get my ph above 7.8 without exceeding 14dkh while using the Oceanic salt. I never had that problem with Red Sea when I used it, or with the Pacific Coast brand we have here. In addition to that, the Oceanic made my cyano
take off and I had a lot more diatom-like growth after switching to it. Actually, I had great readings off the Pacific Coast, it just didn't have as high of cal-mag as the oceanic, and I thought I'd try the Oceanic. Shoulda stuck to what worked!!!
