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.

Protects floors
Size: X-Large: 28" x 34"
I love these pee pad holders. My dog goes near the edge of the pad and the urine gets on my hardwood floors. With these pads the edges of the pee pad holder catches the urine before it gets on the floors. It is very easy to clean the pad holder. I am so thankful it protects my floors!

Works well with the pads. Keeps them from getting bunched up all over the floor.
Size: Small: 24" x 24"
It was a nice idea, but my dogs chewed it up. If you don't have a chewer, then it's really nice.

Saved my sanity
Size: Small: 24" x 24"
I thought I knew everything about cats, but when my 14 year old cat stopped using the litter box, I could not fix it. I did persuade her to start using puppy pads but the problem was she would pee toward the edge and it always got on the floor. Or, defying everything I know about reality, she would find a way to pee UNDER the puppy pad. I asked ChatGPT for advice and it recommended these. They fixed the problem by 80% and I'll take it! These mats help a ton. She still gets some pee on the floor, but it's not the huge problem it used to be. The edge on the mat keeps it contained. And enzymatic cleaner works its magic on the floor. The clips that go on the edges are kinda fragile, but that's why they give you extras.
