Filter FAQ?
Hi,
A friend of mine recently moved into a farmhouse that has a small pond (15 -
20 m diameter, 2 metre depth max,. a little through flow of water). I'm an
aquarium fish keeper, and he asked me about about filtering his water, to
remove algae which I presume is from nitrate/ite build up, and to give
greater water clarity. He has some koi / shubunkins (can't remember how its
spelt). What I'm looking for is do you have a beginners faq or good web
links on how to build a decent, but not too expensive (he's just moved
house) filter. The usual one I have seen is with old hair rollers, and some
foam matting.
Help would be appreciated.
Many thanks
A
