Product description said that Matrix will trap Nitrate also can keep it as biological media, so will it ability absorb nitrate exhausted overtime?
hehehe I'm asking about it cause I'll need to replace my Bio Media soon, if it can absorb Nitrate even just small amount of nitrate then it would be better than nothing.
Why are you replacing biomedia? Biomedia should be good for the life of the tank.

Seachem Matrix is bio media. It doesn't get "full." You use that and you don't bleach it. From time to time if it gets covered in mulm, it's ok to swish it around in a bucket of tank water (not tap water) then put it back in the filter. Matrix has BB in it, so bleaching or rinsing in tap water is forbidden. Matrix is typically placed in the filter.
