I would like to know what the difference is between a pressurized filter and
a non pressurized filter. Is one better than the other? My filter started
leaking and I need to buy a filter for a 2,000 gallon pond.I bought my
filter locally, and had it for about 6 years. It was a regular filter with
no uv attached.Any advice on buying a new filter would be greatly
appreciated. I was considering buying a filter with a UV sterilizer built
in, as I didn't build any shelves in my pond and have tried to grow water
lilies on the bottom of the pond plus a number of other plants a few times
but the koi destroy them, so as a result the water is always green. thanks
for any advise
