A real pain in the neck to clean out!
These Bags are great at what they are intended for... They collect & filter almost everything out of your water. Great water polisher. But in a large aquarium they clog after 3-4 days, and man! they are a pain to clean and re-use,and afer a few washes they are about as useful as as the crud they collect. So its a good idea to have a few extras on hand.
