I've mentioned that we haven't seen our fish for a while. Prime suspect in their disappearance is a Heron who has been around a lot recently, and may very well have made a meal or more out of them. It is also possible that the conditions in the pond are not that suitable. I spent some time cleaning the pond out at the weekend, removing a significant amount of detritus and dead weed. I'd been thinking for a while that the oxygen levels in the water may well be low, and looking for a solution other than oxygenating pond weed (there is already quite a bit of this, and it's making the pond very crowded). The solution is a solar powered pond pump from Smart Solar. It arrived this morning, and was up and running in under an hour. Now I'll just have to wait and see if any of the fish make a reappearance!
