Hanna HI758 Calcium Colorimeter Marine Checker

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

New MiniPipette - The new mini pipette has a 2-stage plunger that will let you accurately dispense your 0.1mL tank water sample. The pipette is spring-loaded and will allow you to retrieve and dispense 100 µL. Just attach the pipette tip, and press the button down until it stops the first time. Then place the tip into your tank water sample and slowly let the plunger spring back up. Move the pipette to your testing vial, and press the plunger down to the first stop to dispense the liquid it took in.

Great for dental appliances
Color: Pink+purple
My daughter has a dental appliance that can get food caught in it. We were told to try a water flosser to get the trapped food out. This has done exactly that. Very happy with it.

Fun new way of flossing.

My 7 year old loves it and it works really well. He’s excited about teeth brushing time again accompanied by water flosser and it can be used in the shower!

Leaks
Color: Blue+red
Water leaks out of the button you press to change out the head so we will be sending back. Other than that it would be perfect, I’m sure it’s just a fluke thing.

High quality quality Fish Oil with No Fishy Aftertaste
Size: 180 Count (Pack of 1), Pattern Name: Omega 3
I like that it provides a strong dose of EPA and DHA in each serving, and the sustainably sourced fish oil is a nice bonus. The large bottle offers excellent value, lasting several months. Overall, this is a high-quality Omega-3 supplement that is easy to take and fits well into my daily health routine.
