    Temporary swimming pools

    Hi all. I will be moving house at some point this year and my new place will not have a pond. The house will require renovation and if I build a pond first, my girlfriend will kill me.

    I planned on buying a large portable pool, the steel frame type. I hae 16 koi, around 30cm.

    I wondered if anyone sees an issue with fish living in these pools for a long time....maybe a year? Other than a big heating bill in the winter, I'm struggling to see an issue?

    I would go for a big pool, maybe 20 foot circle and 1 meter deep.

    What are your thoughts?

    Would be fine you just want to make sure you do insulate in winter etc as the conditions will effect the water very quickly, I had a temporary round pond in my garden this summer when I done a deep clean on the pond and it got to 30 degrees when we had hot weather, was only full for about 3 weeks! Also check your tap water there when you fill it as mine has ammonia in so I had to be careful.

    Thanks. How would you go about insulting the sides of a temp pool?

    This is my pond a 3m x 2m x 1m depth rectangular swimming pool with a black butyl pond liner inside as the blue check would of sent them crazy haha laid insulation below ie on the ground to stop punctures

    clad in timber and as you see for the winter it has poly sheets and a pool liner and tarp cover for winter

    it has run for couple of years, I have three pumps to two filters with two diff outlets, cascade from one filter and three pipes from second gravity filter

    well stocked as you see but have great readings and fingers crossed No issues to date

    Underneath I have cardboard, hot tub foam base, plastic and old carpet pieces

    sides you could use and I would in future some type of insulating board, mine is just timber clad at moment

    on top as seen and as for most some type of polycarb or similar covering

    depends on budget

    obviously a rectangular one is easier to work with than round especially if gonna be semi-permanent like mine is

    Fantastic. Looks great. I didnt think of a timber frame around a temp pool. This would allow insulation to be used in the cavity. This looks a lot nicer too. Good job

    I kept 9 x koi 65 to 85cm and 2 sturgeon at 120cm in a 3x2x1m temporary pool for 3 months while a revamp of the pond happened. Koi were fine, sturgeon were well and truly peeved. 16 koi to 30cm should be a doddle with decent filtration.

    My fish have been in a pool since I moved at the beginning of October. Temp swing is a constant issue but hopefully only a couple more months left till I can move them to their new home.

    They can be viewed here:

    Thanks for the info. Looks like temp swings would be an issue. I will try to get the biggest pool i can to limit this and position it in the shade. Hopefully this approach combined with my heat pump will limit swings.

    Does anyone see any issue with going second hand? If thoroughly scrubbed and rinsed?

    As I'm still building my pond I bought a 3 metre pool and wrapped it in bubble wrap, went round the pond and the temp filter 4 times to give it extra insulation, and up to now all good with the pool and the fish, they have been in there since mid aug 20 and bubble wrapped on the 18 Nov 20. but if you cover your pool make sure you leave some vents for the gases to escape or your fish will be in danger.
    Good luck with the new build mate.
