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.

Wanted something that was going to be lightweight but had those longer sleeves because I do still get a tad chilly even on the warmer days. This is perfect, the fabric is lightweight and breathable, the loose cut around the waist adds to the top's "breathability," but it still keeps you cozy and warm on those chilly mornings! The brown is a lovely warm-coffee tone and it hasn't faded a bit in the wash. Very nice shirt to add to your collection!
