2 PACK LEE'S DISPOSABLE CARBON CARTRIDGES FOR UNDERGRAVEL BOWL FILTERS 13028 NEW
Jun 06, 2016
Simple and effective design
These cartridges are easy to refill with my carbon and zeolite mix. They allow access from the top of my small tank, so especially when I remove some water for a partial change I can also replace the filter as well, then add the fresh water!
