Pumpin’
We’ve been thinking over the last week or so about whether we’re going to have a pump and filter. After visiting Big John’s koi pond and getting the low down it seems if we want water that we can see into in any shape or fashion then we need a biological filter of some sort. Big John tells me that he just has a Grundfos style central heating pump on his system (after a series of brushes and physical filters) in line with an ultra violet clarifier to zap any algae as it passes through.
I must say, I prefer the idea of having a pump that’s out of the water rather than a submerged pump. I’d also like to have some iron pipework with chunky joints and maybe a beefy gate valve of some sort (just for show!).
Time to start Googling…
