Get one, and use as a visual "water tester," not just as a filtration device.
Get one...cut into thin strips...put couple in filter sock (or in water bottle with top cut off, so will restrict flow) on outflow either in tank or sump, and you will get a good additional test of water quality by checking now and then, using color code.
Blue - Copper
Red - Iron
Green - Free Copper ions
Brown - Normal organic load
Black - Heavy organic load
Using clear bottle, you have a ready visual check and one more way to keep eye on water params...
