Looking for some advice from the forum on my phosphate issue. I had been checking my No3 & Po4 with Red Sea Algae Control kit for the past month. My Po4 was pretty steady at 0.12 & No3 undetectable. Since the Po4 wasn't off the charts but steady I let it go. Upon purchasing a digital Hanna tester for Po4 to my surprise my first test was 0.68 did another with similar results. Tested again with RedSea same 0.12. Did a 50% water change and got it down to 0.14 next day back up to 0.29 and sitting at 0.35 now pretty steady. My tank is only about 12 weeks in. I cycled it with live sand, dry (previous live) rock from my LFS, and added live bacteria. Roughly 2 week cycle. I've tested everything multiple times. The only thing I can assume is the dry rock I used is leaching the phosphates.
