How do cope with the freeze Zozo- like what to bring inside?
Actual the fish is most important in my case.. It's to tricky to keep them all winter in such a steel plate above ground tub. I leave tem in as long as possible, but prepare a few large plastic tubs in the cellar. That basket which hangs in the wooden barel is the (trickle) filter. It has a cyperus alternifolius in it, that dies if the roots freez, but indoors it's an evergreen. So that one goes inside before the frost.. And take some aqautic plants and mosses in.
That cyprus is a very good summer helophyte, but it does zip below 20°C Also take 1 Nymphaea inside, also an evergreen indoors. This is the one you see in the barrels picure above. I wont have this much plantmass already in april with leaving it outside.
It depends what my ideas are, last year in mission 2016 i completely started over with an empty tub. But this year didn't just left the tub as it was, only drained and cleaned it a bit after the winter to get most fauling organics out. As said i choose winterhardy plants according to their seasonal properties which start growing very early in the year to get it going early. Like that Iris, flowers from may to july, so you see it already starting to develop plant mass early march, 2 months later is is mature and 10 times bigger this grows like mad. I used it in the tub for years, but my old HDD crashed it has all the pictures from 2012 till now on it.
But this is how the iris looks now in late april in the old 10 year filter bucket. Can't use it anymore it rusted some holes and leaks. But in januari it still was empty..
The other plant is Bog forget me not.
This bucket also has some Schizostylis, they survive the winter, but as a temperate subtropical late bloomer (september) it doesn't grow that fast yet. It still is just a tiny plant. Not much of helophyte for now. It also contain some Pontederia yet not even showing, but will come..
The tubs helophytes this year are the Eriophorum and Bog forget me not. This is what survived the winter and grew back till now on it's own.
The floater is the Nimphoides peltata also came back from a last year leftover rhizome. All very early growers. There also is a purple iris in there, but planted last year, it still needs to mature it's rootsystem. The older this will get the more abunded it will come back each year. Iris is one of the main reasons to completely start over once eevry few years, if this one gets going it has an unstopable rootsystem, getting to much for such a small water body. But that will take 3 or 2 years depending on how much is planted. But that's what makes it a number 1 helophyte..

See the potamogeton natans next to it, it survives the winter but yet not much of a help..
And with this strategy, looking at the season the plants flourish and use that property, i keep it relatively algae free till now.
