Very easy to follow instructions and I like that all the pieces are in a nice sturdy storage container so I don't lose them.

Being a color blind reefer is a struggle! I have switched to Hanna checkers for Phosphate, Nitrates, and soon alkalinity. The Hanna checker for calcium doesn’t get the best reviews and has extra steps needing RODI water and use of additional pipettes, so not as easy as most Hanna products. This Red Sea Pro Calcium is great! The syringe holder that allows you to swirl the vial while doing the titration is great. The vibrant color changes are very clear…and the blue color is one I can see. I have tried other kits that have been a struggle and I really didn’t know what my calcium was. After using this kit…I now securely know my calcium is indeed low, and I have begun dosing now that I can accurately test. My corals look better in just a week after starting to dose! Fantastic product!

Hanna makes good checkers but calcium is not one of them. This is a great choice for a good calcium checker.

Red Sea products are always the way to go! When using these products dosing can be a real guess! But that’s pretty much what I do with these trace elements is guess! corals love it just don’t overdo it! Fast delivery arrived safely
