Hello all,

Thanks for the help with my recent posts. I am new to some aspects of
'ponding' and I have now got a question regarding filtration.

My pond is quite small (250 gallons) but it would be nice to have
reasonably clear water to see the goldfish, specially in the warmer
months when I'm outside a lot of the time.

A friend had donated an OASE Aquadex M6 pump but no UV or other
filtration box and wondered what any of you might reccommend for my
size of pond. Are Hozelock Bioforce any good for example?

With this in mind can you also reccommend the best way to deter herons
too as there is one that visits occasionally!

Many thanks,

John.
