What is it supposed to do?
 
Interesting I'll have to look into getting some.
 
I've used it a couple of times. It's a bag of macro-porous synthetic polymer that's supposed to reduce nitrate and ammonia. It starts off as an off-white colour, then progressively darkens - which apparently means it loses its effectiveness.
The instructions say you can regenerate it with bleach - but I was too scared to muck around with bleach on anything that would go in my tanks. So I threw it out after a single use.

It works well and esp when ur gone on vacation for a while.
 
Its a great product. Recharging may seem scary but its fine ive done it countless times with no issues.

Its great for keeping nitrates low by removing the organics before they become ammonia
