Okay ... now I have to know how big your pond/aquarium is?
Just can't see how it would work with my 3,000 gallon pond
and my water dept. tossing in 3 ppm of chloramine each day.
I even used AmQuel in my indoor 35 gallon patio pond.

Buy a whole house filter, they are not that expensive $100. You
need to change the cartridge twice a year, no matter what the usage,
to avoid bacteria growth. Put it on the line that feeds the hose to the
pond.

Each cartridge should be good for a labeled large number of gallons.
Be sure to get a carbon cartridge.
