Hello, I'm struggling to understand the relationship between alkalinity and calcium levels in my tank. I’ve read a ton about it but I’m still confused. I have a high level of calcium (500) and low alkalinity (7) I’m not sure how to address this. I have B-Ionic calcium buffer system with component 1 alkalinity and component 2 calcium but I’ve never used it. Can someone help me out? Specifically can you tell me what you would do in my situation. I have a 13.5 gallon fluval evo tank. I also have a protein skimmer attached For coral I have some mushrooms and Xenia, a pink birds nest coral, zoas, and some leather corals. Additionally I have a coco worm (hard tube feather duster), a clownfish, 2 cardinalfish, and one tiny goby.
I am wondering why my tank would have low alkalinity but normal calcium levels? My alkalinity is currently 6.5 and my calcium is 440. What’s the best way to fix this? Water changes? I’ve been reading about calcium and alkalinity online but I’m still somewhat confused with their relationship and so I’m not sure how to address this issue.
I have a clarification question regarding my alkalinity test. I have a Red Sea testing kit. I included a picture of the instructions and the reference page. The instructions say to add one drop of the KH indicator to obtain the “start” color. What’s confusing me is that my “start” color is a much lighter blue than the color they show. Should I add multiple drops to obtain the same color they show, and then start counting my drops? Or should I start counting drops right after my first drop, even though my start color is so light? Any help you can provide would be greatly appreciated! I imagine this will be an easy question to answer for someone with experience 🙂
