Love these filters

I buy these filters for my lil tank filter but made the mistake of just a swish a few times in tap water then loaded it into the filter, WRONG

because of how well the filter system I use works.

so I change the filter quite frequently about once a week and these filters suck up all though overage that needs to be removed from the tank
