I am using a carbon filter. Works great.
The charcoal filter is just what I am calling high priced. We use
the filter at our Ink facility to begin the water treatment to remove
organics and chloroamine. $60 to $75 for a 3500 gallon canister(25
pounds of charcoal) is out of reach for a lot of beginners. I use one
for my show tanks in my office, I guess I should just take it home.
So, what's common in the lower priced range for the rest of us?
Hey Charles, could your company be using the wrong product?
The whole-house filters at Home Depot o/e are a lot less than that, and
the replacement carbon cartridges (about 9"X2") are six or eight bucks.
They may not do 3500G, but I found that I had to swap out cartridges
about every 6-9 months when I was doing about 150 tanks and shoeboxes.
It was certainly many hundreds of gallons.
A simple pool chlorine test kit, used on water from a tap between two
such filters, gave me ample warning when the chloramine was starting to
punch through the first filter cartridge. I then dumped it, replaced it
with the nearly-unused second cartridge, and put a new one in place 2.
The trick was to run the water through very slowly, to get complete removal.
I was getting my replacement carbon cartridges from industrial surplus
houses around Silicon Valley, so my costs were often a buck or so per
unit. Even at retail, IMHO, carbon filtering is way cheaper than
"Amquel" or even "Prime" (a less-stable substitute many use). What is
more, it doesn't kill off all those useful infusoria critters, the way
the dechloraminators all do.
