After being out of the hobby for 20 years I plan to set up a 20 gallon
freshwater tropical aquarium soon. I am an experienced aquarist, having
been in the hobby for 20 years.
For ten years I worked at Ed's Tropical Aquarium, a pet store in
Lynbrook, New York.

I want to keep it simple, and easy enough for my 10 year old daughter
Elizabeth
to help maintain. I plan on using an UGF with powerhead, and a power
filter.
Sadly gone now is my favorite line, the Supreme Aquamasters, made right
here
on Long Island. So I guess I am stuck with the more modern cartridge
models.

Can any of them use bulk floss, carbon, and other inexpensive filter
media?

And which brands are quietest? We sold Whisper, Hagen, and Marineland,
all of which buzzed loudly. Are the TetraTec or Eheim Liberty models
quiet?

Recommendations, please...

TIA,
Christopher Platt
