[Coral-List] Need advice with Complexometric method

Hi all,

Has anyone done complexometric titration method to test for amount of Ca in
seawater as a proxy for carbonate calcification? I tried this technique but
haven't been successful with it. The titration endpoint was never colorless
for me and the color change was not a distinct indicator of end point. I'm
not sure how to troubleshoot this.
Please advice.

Thank you much,
