CupriSorb is an exceptional adsorbent specifically designed to capture copper and heavy metals. It outperforms carbon in the swift and efficient removal of copper, making it an excellent choice for urgent copper elimination. CupriSorb effectively extracts all forms of copper, including chelated varieties, maintaining its potency until it changes to a deep blue-black hue. It can be regenerated multiple times. When used continuously, it will gradually remove even precipitated copper from the gravel or substrate bed. CupriSorb enables the care of invertebrates in tanks that have been treated with copper by eliminating the copper leaching from substrates.

CupriSorb is a robust chelating resin that specifically targets copper. Unlike competing options, which are simply cation exchange resins, CupriSorb is effective in both freshwater and saltwater environments, while others may only work in freshwater.

FEATURES:
Highly effective adsorbent for copper and heavy metals
Copper-specific chelating resin
Removes all forms of copper

DIRECTIONS:
For every 600 L (150 US gallons), use 250 mL to eliminate up to 7,500 mg (12 ppm) of copper. Place it in a filter media bag, such as The Bag. To achieve optimal results, position CupriSorb to enhance water flow through it. To effectively address undetectable copper leaching from substrates, keep CupriSorb in use for a minimum of 2 weeks after copper tests indicate no copper presence. It can be utilized in a canister filter, chemical filtration module, box filter, or any area with high flow in a trickle filter.

Good quality
Size: Medium, Color: Navy
I gave this as a Christmas present and he loved it. I was worried when I ordered it that the quality might not be that good, but I worried for nothing.

This is more like a long cardigan sweater, than a coat.
Size: Small, Color: #2 Blackandwhite
This is more like a long cardigan sweater, than a coat. It doesn't have much structure & the pocket placement is too high for a coat. That being said, it's very soft & comfortable. As far as sizing goes, the sleeves run a bit long, but the coat, itself, runs a bit tight. I'm 5'10'' and a small fit me, but I wouldn't be able wear anything very thick under it & I'm thin. It's light & machine washable. I almost kept it to wear as a long sweater, but it looks like a coat ,so I sent it back. If you're very thin with long arms and don't mind the pockets being a bit high, then this could be a very stylish piece for you. Otherwise, I would pass.

i would definitely recommend. stick with your regular size or size up for a less slim fit
Size: Small, Color: Black
I usually wear a medium, I ordered a small based on reading the reviews. I am 150lbs 5’4”. this coat fits great for me personally. it’s not bulky, it’s not baggy. it is a slim fit jacket, definitely more on the slender side. when i raise my arms above my head , the sleeves do come up a bit. I would suggest sticking to your normal size or if you want a less slim fit with a tiny bit more room, sizing up wouldn’t be an issue. the coat is super soft and has some weight to it. i would recommend this jacket, it is warm and a nice piece for formal attire.
