Hi Yan, thought I'd scan this thread for updates, been a while since last visit. Pond looks cool, and the garden make-over is coming on great.
It's getting there hopefully it will be all finished for next year.
Wonder if the cold weather is causing you problems - do you get surface ice? Or is the filteration 24-7 so no ice forms because of constant water moment?
The cold weather is causing little visable problems. I've not seen a fish for about a month. Filtration is running 24/7 and I'm still feeding a tiny amount of food daily just to give the filters something to do. There is no ice on the surface although my air intake did freeze as it had dropped below the water line and got some water in it.
Water temp on the surface is -0.5, ambient temp has been as low as -5. I was looking into covers before this cold snap, looks like they'll just have to tough it out. Shortest day today so things can only get better.
I guess ice expansion can cause damage to the filteration pumps & plumbing. Shame you can't use anti-freeze
(Thinking about that, I'd better put some in my car!)
Cheers.
