Ok, this is second season of mine tub pond with siporex walls , on terrace above garage.
It overwintered fine but i had to do some work before filling up
Some paint was in order
... and plumbing work
From last year i had some cane
In tub i put a layer of heavy loam from basement and on top of it gravel to try to have a clear water. Of plants i put mentioned cane and dug up some water iris on friend`s uncle pond. And had some water lily too from last year
It should flower soon
Ive got first visitors too
So, i was browsing a store one day and found this
Sometime later friend sent me some water solider
and some other plant , i think its from Nuphar family, close to water lily
This is situation in tub how it looks now... Im really satisfied... Water is a bit more muddy than usual because i was doing some rearagments. That bit of red are three gold fishes, i cant have more because they will have to overwinter in aquarium. But i have youngsters also.
I think this is a great idea. It a great way to recycle that used tub from some remodeling project instead of sending it to a land fill.
O, *that* old tub from 60s wouldnt end up on land fill in any case since its made of cast iron about 1/2 inch thick. People who are in scrap metal bussines would have been very gratefull if i shoud give it to them.
True, this white walls seems too plain and soon as i get some money i will do something about it. You were probaby thinking about something that is in croatia called "kulir" or little round stones mixed with cement and put on some wall. Something like this
Well, i was thinking to try one winter without draining/dismantling the tub and with 3 goldfishes in it (theres one youngster with them too). Water column is about 12 inches, a bit shallow for fishes but will see in spring how all panned out.
Tub is old and made of 1/3 inch of cast iron, so i dont expect cracks, but checking regulary.
Its not really so cold here in Croatia (as image of ice would suggest) but these external ponds freeze much more that dug-in ones and they need much more time to unfreeze. In dug-in ones a earth is keeping it warm.
But all that ice is almost melted since temperatures are now at average about 40F
