    Post Advice i must know before building my first pond

    Hello , i am looking at building my own pond in my back garden. I have a rough idea of what size, depth and shape i want but i would muchly appreciate if anyone can give me any guiding advice to help me on my way with building my pond and what sort of maintenance schedule i need. i have kept tropical fish for years. But what i have researched on the koi hobby sound a lot different to that

    Pond Size 8ft x 8ft and 4ft deep
    I was thinking on using Sleepers to structure my pond.


    Many Thanks

    My first advice would be to read through some of the build threads on here, picking out those that are similar to your plans.
    My second advice would be to visit a pond locally for a first hand look see.
    Lastly, be prepared to spend much more than you first thought.

    Good luck with your project, it will be rewarding but go into it with your eyes open and well prepared

    Hi and welcome to the forum .

    Good advice from Alan . There`s a lot to think about so do as much research as you can before you start , to give you an idea of the options .

    One `mistake` most people make on their first build is not going big enough for the fish you end up with . I worked out your volume at around 1500 gallons - which is a bit on the small side . So I`d say try and go bigger if you can .

    Also , work out your budget , you can keep maintainance lower , if your filter system is good - but of course , you`ll pay more for this .

    Good luck and keep us informed with your progress

    Build it as big as you can because in a few years you'll want bigger!!
    Then you'll need to rebuild the pond, buy bigger/better filters, need a bigger shed to put the filters, have *discussions* with the other half on how youre then going to find the £8000 to do it, not want to spend money on anything else..........You see where im at?!!

    I only wanted to start off small so I didnt overwhelm myself with how much work and maintenance has to go into it.

    But I could always tell the over half to move out to make more room Advice i must know before building my first pond

    my advice is to seriously consider why you want a koi pond!
    Maintainance is the biggest part of koi keeping if your on a budget

    I'm on about maintaining it when I finished the pond , not about having a minimum maintenance for the start

    I thought the biggest part of keeping koi was being a microbiologist and water quality scientist
    4600 Gallon Concrete Block and Fiberglass
    2100 mm x 710 mm Infinity Window 32mm thick
    2 x Aerated Bottom Drains and Skimmer
    Filtreau HiFlow 30 Drum Filter
    Bio Chamber - 140 litres K1
    Bakki Shower - 30 KG Sakura Far Infrared Media
    2 x 18,000 lh pumps
    Idealseal MS290

    I think if you go down the anoxic route then water bills are less. You could use an airlift to move water - this can mean you can switch off the pump and let the air pump do the work. This can be as good as 39W for 15,000lph compared to a pump being at least twice that. Depends heavily on the design of filter. A 280W solar panel plus inverter could help reduce the power needed further - cost second hand can be worth it.

    If you're using a sponge filter - I would 1/4 the filtration rating that manufacturers give. I eventually gave up on a 9000l rated pressure filter on a 1700l pond. The issue being the pond being in full sun derates the filter even further due to the suspended algae.

    You can DIY yourself to good filtration. Have a look at "Wrighty"'s YouTube channel.

    Oh and as RoyLittle has said - you'll find yourself considering a microscope (£120-140) a good buy.. Brunel SP22 or Apex Practitioner.

    I have seen lots of good reviews about the evolution aqua filters? Are they any good.

    And the water or electricity Bill's ain't an issue if it means my koi are getting good care

    Hi, welcome to the forum and the hobby. advice?, well, it has been said: go as big as you can. this also means down. depth is important to koi., also it help keep a more stable temp. in winter., so go 6ft if you can. ( 3ft down/3ft up, or siilar). and that is depth of water , not depth of pond.
    i would say 4,ooo gallons is a minimum. koi need lots of space, and a large volume of water is easier to 'control' with regards to filtration/medication/temperature etc.
    a bottom drain/gravity fed system is parampount. fibreglass (insulated concrete & block) is the best liner option, 2nd would be a fitted box liner., i wouldn't even go near a normal pond liner.
    filtration could be anything from Nexus/bead/shower etc, maybe avoid any type of pressure system.
    look at as many plans and options as you can, and speak to as many pond owners as you can, go see lots of ponds.
    so as a starting point i would look at laying as big a concrete base down as you can, as deep as you can/need, and work from there.

    Iíd agree with other comments regards plenty of research,there are a lot of tried and tested methods which are well documented and easily accessible,At the same time thereís no need to over complicate things or do everything on an elaborate scale,there are some who would have you believe itís all rocket science and to succeed youíll need the biggest pond with the most eye watering expensive equipment but itís not the case at all,thereís no reason why you canít build and maintain a healthy pond quite easily and on a modest budget especially as youíve got experience of fish/water keeping already

    EA? That depends. You'll hear lots of dealers talk about them. However their ratings (things like easy pods) are well over inflated. Cheaper base price with no moving parts I suppose but most people fit a drum in the things anyway!
