I am about to build a pond, and I know certain other members are planning something similar. I think it would be wonderful to have a thread where we could discuss our pond projets and (hopefully!) get some input from experienced pond poeople.
On that note:
My pond is going to be 740 litres, preformed, which is roughly 195 US gallons. It's going to be 2ft deep, which will hopefully protect the fish from the winter temperatures. I'll be adding them during the height of the Australian summer, so they'll have plenty of time to adjust.
It will hopefully be the new home for my sister's comet (currently in a 23 gallon), along with a comet of my own and a shubunkin. If possible, I will persuade a friend and student to part with her two comets (currently in an unfiltered, neglected 5 gallon with a fantail, despite the fact that I bought her Prime, Stability and a decent filter for Easter). It won't help the fantail, but at least it will be better than all 3 goldies in one tank. If possible, I may be able to rehome the fantail, but none of my tanks are suitable as a long term home for it. But maybe I can heat the pond so it can live there?
Anyway, that's a ramble.
I will have to buy my own pump (roughly $250+ AUD), so I want to build my own filter. I have a 12 litre bucket that I'm going to pack full of cycled filter media - I plan on lots of wool, lots of ceramic noodles...any other suggestions? I don't think I want carbon (so expensive) but if people think it is best I will. I was going to put gravel of various grain sizes in there too.
For the bottom of the pond, we have a nice bag of large river rocks. I want to attach some pots to the side (somehow) and grow some semi-aquatics, like mondo grass and violet. For inside the pond I'd like some good pond plants - maybe rush? - and maybe a rock structure for them to hide in.
So, that's my plans. I would love to hear suggestions and/or criticisms, and plans from other people for their ponds! :) Also, if anyone could tell me how much maintenance this pond would need in terms of water changes, that would be great. :)
