Brightwell Alkalin8.3-P 500g - ALKP500Highly effective alkalinity increasing (buffer) powdered blend. Helps increase pH stability in an aquarium by raising the alkalinity; continued addition raises pH until 8. 3 is reached, at which point the pH remains unchanged and the alkalinity alone increases. Provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef building organisms as skeletal material. Formulated by a marine scientist.

I love this shirt. it is good quality. I got the clay colored one. I really like it. They do run small. I normally wear a medium. So I got a large. It fits pretty well. It is a tad bit tight, but I am losing weight(145LBS) So far. So it should fit fine in a few weeks. I am 5,2 135Lbs. I probably should have gotten the XL.

Slim fit for the winner

Size: Medium, Color: Clay Floral Print

Beautiful orange shirt and I love the metal buttons. Very comfortable and I like the slim fit. It appears more tailored. I'm a tall guy at 6'4" and the length for a medium was perfect.

Ten years of ownership…Thank you, Timex!

Color: Black, Size: One Size

Solid watch for everyday wear. I have worn this watch for over 10 years. I let a watch shop replace the battery about every 18 months. Other than the original band (which lasted 5 years) I have had zero problems. Still looks great, rugged and manly😇 Overall I recommend this watch for its value, reliability, simple clear design, legible hands in all light conditions. Great watch!!!
