I need some assistance on getting my dosing accurate for my reef aquarium. I've been struggling keeping my alkalinity at 8.5. Every time I think I have it locked in, my numbers tend to drop. Even when I make minor adjustments, the all will climb to 9.0. Make another adjustment, and it will drop slowly, but continue to drop past 8.5. So I tried a test that my LFS recommended. Turn off my DOS for 24 hours, then test after the 24 hour period. Run the Seachem Dose Calculator and use that amount to set for my DOS. The problem is, my alkalinity dropped from 8.3 to 7.4. When you enter that into the calculator it wanted me to dose over 100ml per day. That's almost double what I typically dose. My Trident is almost always inaccurate, so I have been using the Hanna checker. Now I'm not confident my results are accurate with that either. I have some really nice Acros, so I really would like to get a handle on this.
Any suggestions?
