    Basic advice needed !!!

    Hi thanks for taking the time to read, I've just inherented my Dads two koi, they are about 18 inches long, they are currently in his fibre glass pond where they've been for the last 15 or so years, mum can't look after them so I've decided to build my own pond!

    I've no experience with koi except cleaning the filters on the pond. The current setup consists of a submersible pump, drawing the water through a UV light, then onto a filter ( grey round tub with plastic bits in) the water passes throughput the plastic bits then exits via a central bit in the grey tub back to the pond.

    Also there is a standalone submersible pump just turning the water over, along with 4 air stones

    My questions are.

    Should the new pond be square/rectangular or circular ?

    What size ? Not too interested in adding more fish but just want to look after the two in his memory.

    Will the current filter work with a bottom drain ?

    I'll add a pic of the setup later.

    Sorry for the vaugnes and questions any help much appreciated.

    If you are going to build your own pond, chances are you might get hooked on the hobby lol. Any shaped pond is ok I suppose as long as it's done right. The filter might work, but how well do you want it to work? Many filter systems are available that make life a lot easier for koi keeping, it all depends on what you want really.

    Do you have any koi shops near by? Going to see setups and getting advise on them is possibly a good idea.

    Thanks for the reply, I'm near Taunton Somerset the only koi place I knew was blagdon water gardens but I think that's pretty closed down now.

    My main aim is to make it as easy as possible to look after and enjoy them ! Any suggestions on filtration etc greatly welcomed.

    If you want the easiest to maintain the way forward would most likely be a drum filter, fluid bed and possibly a shower. But, drums are not cheap, however they will vastly improve water quality and cut down on maintenance drastically.

    Just to add, when you do finally get the pond made don't move the fish straight away. It might be a pain having to maintain the old pond but new ponds take a while to establish and I wouldn't like to see the fish you are doing this for get sick.

    Get some other smaller fish to get the new filter cycled as putting those large fish Into a new pond without a mature filter would cause water quality issues, ammonia and nitrite spike which are bad for fish.

    Thanks for the reply I'll take a look at the suggestions, would you suggest some small koi ?
    How long does it take for the filter to establish roughly?

    Some small koi should be fine, you would benefit from getting a water test kit to see how things progress though.

    As for the pond/filter establishing it can take some time. Different media's seem to take varying amounts of time but temp also plays a factor.

    Thanks, do you think it would be possible to move the filter unit from the old pond to the new one ? How could I maintain the quality of the water in the old pond whilst the new one establishes ?

    You could move the filter from the old pond to the new one, but without it the fish will get sick from high ammonia, possibly nitrite poisoning, but if nothing is converting the ammonia nitrite wont be created.

    Here is some info about what a pond filter system should be doing.

    I think it would be helpful to have an idea of budget?

    Definitely....^^^

    Budget is a big factor, but if you are handy you can still build a decent pond on a reasonable budget. I reckon my first 7000 litre sleeper constructed Koi pond was well under 2000 including a brand new Nexus 220 filter. But on the other end of the scale you could spend 5000 just on a filter.

    You could build the new pond all set up with a new easy-maintenance filter system, let it settle for a month or so, and at a time when the PH and temperature match your Dad's pond you could transfer the filter (the one with all the plastic bits) and the fish over to your pond, running both your dads filter and your new modern filter at the same time.

    The old mature filter will be dealing with ammonia and nitrites whilst your new filter begins to mature. After 6 Months or so you can then shut down the old filter.

    What size pond would you like to build? That'll be an important factor when getting filter recommendations.

    Thanks for all the relpys much appreciated. The construction cost of Building the pond will come in with the house build. I was thinking on reinforced concrete base 100mm thick, block work walls laid on flat, 3.0m X 2.5m 5ft deep (2ft in the ground) . Finished with sand cement render and topped with koi paint.

    The main expense will be the filter and UV so recommendations welcome !!!

    Once again really appreciate all the comments
