    Pond Rebuild and Questions !!!

    Hi all

    I have a 2000 gallon linered , pump fed pond that I built about 16 years ago and moth balled about 4 years ago when the dreaded Heron decided it would use my pond as its dinner stop.

    I'm just starting the rebuild, changing it to a bottom drain and concrete / block built and bringing it out of the ground. Size wise it will end up at about 2500 gallons. In the past I have used a cloverleaf style filtration system but have used and still used a Nexus Easy pod on a 300 gallon Quarantine tank that just had goldfish in but works extremely well and fairly easy to maintain.

    Filtration wise , I have looked at a larger Nexus easy Pod 220? or moving to the new Drum Oase Profi Clear Style of filter system. I would prefer a low maintenance system. Any thoughts.

    Bottom drains - I have looked and read on line about the Spindrifter aerated bottom drain and a make JBR ?
    Questions -
    for this sized pond it looks like one drain will be sufficient ?
    I'd go for a separate pipe for the air but cant get my head round how this will work ? has anyone got a link to a video or article that describes how it will work ?

    Also any other big pointers - considering adding in some kind of heating system - not to be all singing and dancing but just to avoid the problem of a freezing pond over winter.

    Will be lots more questions a we progress.



    Thanks in advance

    Graeme

    Hi and welcome to the forum

    If you have a read up on some of the build threads you will get some idea on equipment used, if you want low maintenance and can afford it then a drum filter is the best option imho, you should be fine with a single bottom drain

    As for pond heating, the best option it to insulate and cover your pond, this will be the first step to stop any freezing, you can then, if needed fit an electric heater in the pond or have a system that works off your central heating system, which is what I am doing

    Hello mate. I have the spin drifter bottom drain. Has 4 inch hole which is your bd pipe
    Alongside it. It has a 1 inch line. For 1 inch pipe. Air line. So when the pipe goes to filter place. You get these in the link. One goes end of pipe at air pump. And one fits
    In the 1 inch pipe end under your bottom drain dome. Solvent weld glued in.The dome stem should have a air nipple screwed in. Then you fit air line tube to both nipples. Under your spindrifter dome.
    Same from pump to other end of 1 inch pipe

    Thanks Roy

    I actually joined the forum in 2016 when I had the Heron problem but never posted only read !

    Am favouring the Proficlear Filter at present and within budget.

    When you say insulate would you mean when building ? putting is some kind of insulation in the walls - am intending them to be block built then filled with concrete ?

    For heaters there seem to be a variety such as https://www.cotswoldkoi.co.uk/produc...saAgg0EALw_wcB

    These I assume would be fitted to the return water pipe ?

    Hi Graeme

    You can get inline heaters or in pond heaters, the inline one will distribute the heat more evenly, mine is inline but off my central heating system

    When you build your pond you can insulate on the inside with a foam sheet, mine is only 25mm but itís a thermal barrier between the pond and the outside, you can then either fit the liner or fibreglass straight to the insulation

    If you have a look through my build thread you will see what I mean about insulation

    Yep - understand it 100% now - I was thinking the pipe would just fill up and you'd have a small tube running though it.

    Thanks

    Hi Graeme,

    Welcome back to the Forum.

    I run an Oase Profi and have a JBR BD - both I rate highly.

    If budget permits Oase all the way for me pal.

    Cheers

    Ok decided on bottom drain and know how to fit the airline etc.

    Filter wise - Will be going for the Oase drum style

    Looking on line there are three that are very similar and similar price.

    Oase BioTec Premium 80000 EGC Drum Filter

    Oase Bio Tec 80000
    Oase ProfiClear Premium Compact-M Gravity EGC

    Are they all the same or are they different - if different is any one better ?

    Next Stage is the return of water - is one return normally ok and in the water about 12 inches below the surface and if the pond is Kidney shaped is there any particular wall it should go on ? Next post will be about skimmers and position on how they work but will do a bit more research first.

    Hi Graeme,

    Firstly great decision on the BD.

    In respect of the Oase drum, the immediate difference is the biological media. The 8000 has sponges and the PC has moving bed K1/Hel-x.

    Personally despite any manufacturers claims, I believe both in isolation will struggle biologically to cope with a 2500 gallon koi pond.

    Very happy to discuss with you.

    Cheers

    Adding a few photos of the old ponds. I had one koi pond and one natural pond.

    Rebuilding that side of the garden at the same time as next door have just knocked the house down and built a new one and put a new wall in on the boundary.

    I'd forgotten how well the old pond had been built - 18 years ago - concrete ring at the top then rendered then linered !!

    Photos attached of work so far.

    Before I try and post some more pics are there any tips/instructions to get them the right way up ?

    I've tried a flickr account , rotated photos , cropped photos but have come to the conclusion the site doesn't like photos originally taken in portrait mode.

    However think I have a work around.

    When digging out the old pond we discovered that alongside the old pond was a water feature dating back to the 1800's when the land was part of the gardens of a very large house. It also explained why the pond would always gradually fill up , as there was a natural run of water into and under the old pond.

    This has meant quite a bit of extra work redirecting it into a sump I have at the bottom of the garden to clear excess water. ( The bottom of the garden is below the road level sewers so has to be pumped to the front of the house and then up by another pump).

    Some photos to follow (hopefully the right way up).

    As I have the excavator on site and can change the pond to whatever shape I like, can I have some pro's and con's as to whether I keep it Kidney Shaped - possible fits in better with the shape of the garden, or do I go for rectangular or do I go for flat back and curved front.

    Would like to put a window in the front but need to get some ideas about the returns and the flow of water round the pond.

    Approx size will be 4 x 2 x 1.5ish approx 2500 gallons - single bottom drain and then return - (one or two) ?? plus a skimmer.

    Filtration likely to be an Oase Profi Drum filter - not sure quite which one yet -depends on how on how much money I have left after the extra work I have had done.

    Nice progress, If your pond is long and thin, would you be better with two bottom drains? I would always go with two returns as it gives you options to change the flow of the water if you have to

    Agree with Roy, I was advised to put in 2 drains but didnít, mainly because I couldnít afford a drum with more inlets at the time.
    I wish Iíd listened and put in the extra one. My pond is more or less 4x4 (just under) and the corners donít quite get the pull from the drain situated in the middle.
    Other things I wish Iíd done are slope the pond bottom toward the drain and chamfer the corners off.
    Saved some money but have compromised the detail.
