I have 2 ponds and they are getting a bit silted up. It's not really practical to drain them to clean out the silt, so I'm considering buying a pond vacuum. I've been looking online and the Oase Pondovac 4 seems to be head and shoulders above the rest, but it is pricey and also possibly more powerful than I really need.
So I was wondering if anyone has a pond vacuum that they would recommend or, indeed, any views on the Oase Pondovacs?
