API pH Up

API pH Up is a pH adjuster that raises pH levels in aquarium water to make it more alkaline when levels fall too low.

API® pH UP pH adjuster raises pH levels in your aquarium to make water more alkaline when levels fall too low. pH is the measure of acidic or alkaline conditions in water, where a value of 7.0 corresponds to a neutral pH, pH values about 7.0 are considered alkaline, and pH values below 7.0 are considered acidic. Different fish need different pH levels to be healthy, so it is important to test your water regularly to ensure pH levels fall where they should. pH UP pH adjuster is fast-acting, colorless, easy to use, and will not cloud aquarium water. Because it is phosphate-free and nitrate-free, pH UP pH adjuster will not encourage algae growth.

Instructions
Determine the pH of aquarium water with an API pH TEST KIT. To raise pH, add 1 ml. for each 10 gallons of aquarium water. Take another pH reading before adding another dose of pH UP pH adjuster. Some fish may be sensitive to pH adjustments greater than 0.2 in a 24 hour period, so changes of this magnitude should be done with extreme care.

Protects your mattress from toddler spills!
Size: Full, Size: Full
Writing this after my toddler spilled a ton of water on my bed (a new mattress). I didn't realize what she had done for about 1 minute. By the time I got her off the bed, pulled the sheet off and pulled the mattress protector off, the mattress was still dry! I felt the bottom plastic part of the mattress protector and could feel the coolness of the water, but not dampness. This thing works! Note, I don't know how it would perform if I had left it for a really long time. The protector is also very soft on top, not noisy, and easy to stretch over the mattress. You can kind of see the square shapes of the protector through the sheet, but I personally don't care. It was a great buy.

Good fit
Size: Queen
Covered the mattress well. It was not noisy. Sheets are wee bit oversized and the the cover helps keep the sheets from sliding around. Kids are older so it’s more for the pets. I do recommend it.
