Hi Russell
Is the owner of this pond an experienced Koi keeper?
Garfield

Those bottom cornices

Gunites the only way to go.

Garfield

Hi Russ, did you do all the copper work?

Are the feeders for home use?

Garfield

What finish do you apply inside the ponds?

Does it require maintenance after a period of time?

Like a bitumen sealer.

Garfield

All very carefully thought out.
Very impressive Russ.
The building appears to have been a perfect find for your fish shop
When will you start stocking?
Will that be with the fish you have just bought in Japan?
Garfield

Oil would have been nice

Quit useful.

Garfield

Sorry, I left out the temperature of the soil under the building slab in winter.?

Garfield

Hi Russ, If I recall the pipes are +-110 mm OD. Would it not be beneficial to lay 110 mm polystyrene down around the pipes and pour the concrete on top of the styrene to allow the concrete to act as a heat sink. What would the under the floor slab be in winter? Just looking at the cost and effective...

Hi Russ,
How thick is the insulation?
How thick is the slab?
Could you have saved two elbows and used a 45 on the 2nd bottom drain?
