The chemical composition of Calcium Reef Minerals is designed to replenish calcium deficiencies and sudden drops in seawater. Its use is safe and allows for a quick and effective increase in calcium levels in the marine aquarium to its optimal value.

  • Helps maintain the proper salinity level.

  • Stabilizes carbonate hardness.

  • Promotes the growth of various marine organisms, including corals, calcareous algae, macroalgae, and bacterial biofilms.

  • Calcium carbonate acts as a buffering system.

  • Promotes the growth of calcareous algae.

  • Adding 10 ml of Calcium Reef Minerals increases level by 20 mg/L (ppm) in a 100 L marine aquarium. The maximum safe daily dosage is 10ml per 100 liters of water.

Every aquarium is unique, and dosing depends on the coral population and the individual needs of marine animals. Providing the appropriate amount of minerals is crucial for the well-being of the animals, so dosing should be properly adjusted and modified based on regular water tests at the Reef Factory LAB laboratory.

Starts off very cool
I got this pillowcase for my husband because he is always hot at night and has trouble falling asleep because of it. The fabric of this pillowcase feels very similar to a cooling pillowcase that I have had for years and love (but is discontinued, so I can't get any more of them). It is a silky smooth, not-quite-satin fabric that feels initially very cool to the touch. It fits on a standard size pillowcase, and has a slight pocket end (not very much overlap, so it does come untucked during the night). My husband reports that this pillowcase is very cooling right when he goes to bed, but after a short while, it warms up and isn't really cool anymore. So if he doesn't fall asleep right away (and he usually doesn't), he has to flip it over. His head puts out a lot of heat at night though, so the pillowcase might stay cooler longer for others.

Doesn’t stay on the pillow.
Color: Gray, Size: Queen (2 Count)
The concept is there, but the pillow case doesn’t stay on. Every night the pillow case slides either half way or completely off the pillow. If it stayed on I would love it
