I would tend to disagree, if the Koi choose to spend a lot of time at the other end, at night " sleeping " ( they rest, rather than sleep ) there will be a lot of mulm ( sh.t ) and no bottom drain !
In reality it doesn't travel well along the bottom !
and if you make it too steep, the solids will be left behind !!!
( see building regs re drains, the slope of a soil pipe has to be VERY gentle for this reason !!!! solids left behind )
A modern state of the art Koi pond, professionally built would not have any slope ! ....... maybe a shallow bowl approx 1 metre in diameter around the bottom drain cover.
If you go on EA website
www.evolutionaqua.com
and go on the technical support part, send them your measurements and photo's and explain you have purchased a nexus eazy etc. and ASK THEM FOR HELP AND ADVICE ! they will be surprisingly helpful !
I'm no expert, but I think you may well be contravening building reg's by siting the pond wall so near to the conservatory wall,
I think it will cause problems with damp,
the conservatory wall looks damp now ! without the airflow the problem can only be aggravated.
Until you stand right next to the glass, you won't in fact see the nearest 2 or 3 feet when sat down ( try putting a pole up to the water surface height and sitting in the conservatory, to see where you can see it ! you may get a surprise ! )
Is the pond away from any drains for house, conservatory, next door ?
A building regs inspector has the power to make you dismantle the pond !
How do you intend to reinforce the base and the wall ?
What do you intend to do with the hollow blocks ?
What do you intend to put under the concrete ?
How high is the water table ?
Are you going to have a sump around the pond and sump pump ?
Dan, PLEASE don't think I'm trying to be a clever sod !
I thought of sending you a pm, but the idea of the forum is that we help each other, and learn from our mistakes, and we've ALL made them, not least me !
but I'm getting the impression some of these things have NOT been thought out ?
Peter.
