old pond, old pump
Hi
I have just bought a house with a fairly small pond 15ftx6ftx2ft and a
couple dozen goldfish in it. I have cleared out a lot of plants and
sludge - I don't think the pond has been cleaned for years (it is lined). I
found a OASE Aquarius 2500 pump in the bottom. Can anybody tell me what
this is? Is it a filter? What can I do next to help the fish?
I have kept tank fish before and know how dirty the bottom can get and I am
worried that the pond may need cleaning urgently
Thanks
