You don't need telling, but keep an eye on the kids. I have just cracked mine with a pick axe to help...............
I wouldn't break the ice on it with anything because of the fish.
My own smallish pond is next to the greenhouse and I run a small fishtank airpump/airstone all year round. It mostly keeps an ice-free area , but even when frozen solid the bubbles soon re-make the hole. I had the idea to grow watercress on a small raft floating on the pond, above an airstone. So far it has worked extremely well. :)
Hi Lou,The raft is made from polystyrene, about a foot or 14" square and an inch or so thick, with a piece of thin ply (which may not be necessary but it hid the white colour of the polystyrene), on the top.I cut a hole through the middle of the raft, the right size for a net pot to sit in.... and that's it. :)I have anchored the raft so the air-stone keeps bubbling away directly underneath it.The watercress came from the supermarket and rooted really easily and without any trouble at all and is growing and growing. :)
