Hi all,

I am just in the process of supplementing with Ca and Alkalinity using the "A Homemade Two-Part Calcium and Alkalinity Additive System" article that Christyf5 points to in her post.

I already have a dkh test kit made by aquarium pharma, and I need to buy a Ca test kit. I know that all of you say that Salifert is the best, and Hagen is the worst. What about the middle range?

I would like to buy the aquarium pharma Ca test kit. Anybody has any experience with that specific test kit?

Please let me know.

Thanks
fresh.
