testing Ca
 

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

I'd just get it over with and fork out for salifert,they are worth every penny.I can't tell you anything about the other one.

The salifert is just so easy, I can't imagine saving a couple of bucks anymore to deal with the extra drawn out time the other kits require, particularily the Hagen kit.

I use the AP one until I buy a monitor... at $16.99 it lasts about 6 months testing 2 - 3 times a week... and is accurate to +/- 20ppm... I have compared my results to Seachem's much more elaborate, (and expensive) kits, and found it to be bang on... just my 2 bits...

Make sure to test and adjust magnesium when doing your water chemistry tests. Magnesium levels should be between 1280 and 1350 ppm. I keep mine on the higher end and have great coraline and LPS stony growth.

Salifert makes an excellent Mg test kit :biggrin:
