I'd like to make an inline anti-bacterial UV light filter for an
aquarium by housing it inside a plastic pipe. The lamp element shines
UV light into a glass tube with the water flow. To get the most of
the UV light I'd like to line the inside of the pipe with UV
reflector material. Aluminum foil come to mind. Is there a correct
material or a better material for the reflector?
And while I am on this subject I intend to use paper coffee filters
to trap the particulate waste. A bank of them should be able to
handle the flow volume. When any filter is clogged I'll just toss it
away and put in another one. The commercial filters using fiberglass
wool, etc. clog up too quickly and are expensive to replace often.
Any anticipated problems with this coffee filter approach?
When doing research on the subject I learned that areating the water
with airstones dissolves too much oxygen and drives out the CO2. The
lack of dissolved CO2 prevents the aquatic plants from thriving. That
explains why I had so many problems with aquatic plants dying on me.
There is also a need to have a filter stage where ammonia can be
removed by ammonia eating bacteria. Where is the best place to put
