Hanna HI758 Calcium Colorimeter Marine Checker is used to accurately check the calcium level in reef tanks.

Accurately check your reef tank's calcium level with the Hanna HI758 Calcium Checker.

Three simple steps to results. The Hanna Calcium Checker bridges the gap between simple chemical test kits and professional instrumentation. Accurate, affordable, and easy to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the Hanna Calcium Checker, press the button, and read the results. Done.

Easier to use and more accurate than chemical test kits.

Tips for accurate results:

  • Use Hanna HI70436 Deionized Water
  • Make sure testing vials are clean of any debris
  • Vials must be dry on the outside with no fingerprints
  • Violent shaking will cause microbubbles that can affect the reading
  • Do not let the sample sit too long before taking a reading

Durable and Rugged
Color: Black
I've had it for a few weeks now. It was a replacement I bought after buying several vinyl type covers. This one is a good gauge of plastic and rubber. The rubber seems pretty strong and it protects the iPad well on the corners and back. The back is mostly covered except for the Apple logo in the center. In addition to protecting the corners and also protects the camera lens as the rubber after insulation is a little bit higher than the lens so when you put this down, it's not going to scratch the lens. It has a pen slot, which I like and plenty of room to grip the device if I'm carrying it from place a place or when I'm using it, I can grip the edge and not touch the screen. One of the things I would've liked included is a screen protector, but nothing covers the screen. I also miss the folio type cover because the screen will gather dust now. But, Apple screens are fairly durable so I'm not too worried about breaking it. It was easy to install. It came in as it came in a couple of pieces that you just pressed together. All the controls are obvious as they are under the rubber, but they look like keys. One more thing I might bring up is the charging port. It's easy to get to even though it's a little deep. On my iPad the touch sensor is on the on off button and it is a little harder to do than if I didn't have any case on it, but that is to be expected. It also has an easel that unfolds from the back if you want to sit it up, but I don't use it for watching anything since I have a real TV set. So far I like it and I'm glad I bought this as I don't think it's going to wear out as quickly from me handling it as the others did. The value was good as long as it lasts.
