Do these need to be calibrated regularly?

Replace the reagents about once a year. About $8-$10 each. Calibrated? No.

Is there any other testers needed to test the quality and levels of the water in the reef?

This was a complete kit. But in recent months, Hanna now has released a Nitrate test kit that I haven’t got yet. It’s on back order

Can you mix the testers to the ones i need? I already have most or all but one.

That reef kit kit only comes with those. You can buy separately.

Accurate and worth the money

Hanna is the most accurate and the best quality. I use it several times a day, worth the money. It functions great and is not too difficult to figure out.

Great testers!

I especially love the salinity tester. So quick and easy to use. I love it so much! I wish the Calcium tester didn't have so many steps but otherwise all checkers work out fantastic!

Great for beginner or advanced

Amazing accuracy compared to the api testers. However you have to follow the directions to the letter for each test.
