Been a steady couple of weeks progress on my pond build since I first posted on 10th January – http://nishikigoi.life/2019/01/10/new_pond_build/.

First task was to fit the twin wall polycarbonate roofing sheets to the roof.

With the roof installed the changeable weather presented less of an issue should it rain when the concrete base was booked to be poured.

Having allowed the concrete base to cure for a week one of the biggest days for the project arrived on Wednesday 23rd January when the tank was scheduled for delivery.

If I’d measured the tank and space once I’d measured it 100 times to ensure it would fit.  However, every time I looked at the tank, or the space, the tank seemed far too big.  When my brother had seen the tank at Manor Koi he declared there was surely no way it would fit.  On the back of the truck I was still filled with trepidation.

Thankfully all concern disappeared as the tank slid onto the concrete base with an inch to spare either side.

The tank, estimated to weigh around 500kg, actually slid into place surprisingly easily on a pallet trolley, and even shuffling it across half an inch to meet the wall was quite simple.

With the tank in place the rest of the week has seen the side panels installed and the fence reconstructed.

A massive thanks to Manor Koi (http://www.manorkoi.com) for building the tank to my specific sizes.  The sides are all insulated in a bid to preserve and stabilise water temperature throughout the seasons.

Interestingly the hot question the past few days has been ‘are you heating the tank?’.  I’m really not sure why that question is of such interest to be honest, however, I’ll answer it here.

As mentioned, the tank has been insulated to preserve water temperature.  Coupled with that the tank and filter are completely enclosed within a Koi house of twin wall polycarbonate.

Naturally, the water should remain much higher than a regular outdoor pond would, both summer and winter.  Exactly how the pond temperatures will work out will only be known once it is up and running, even just the brief winter sun through the roof makes a noticeable difference even though the Koi house is very much open still.  So, for those with an interest in that, watch this space.

For the next week my mind shifts to the All Japan Koi Show in Japan.

Upon my return the first task will be to construct the raised platform at the front of the tank to enable easier access for viewing, netting and maintenance.  The same raised platform will cover the bottom drain pipework, and also provide the base for the Nexus.

The tank will utilise one of the new Evolution Aqua Varipumps, probably the 20,000 litre model, which will then offer the flexibility to control the water flow as required.  Read more about them here – http://nishikigoi.life/2019/01/27/evolution-aqua-launch-the-new-ea-varipump/.

Needless to say I’m chomping at the bit to get everything set up and running, indeed I’ve had to resist the urge just to fill the tank with water just to see what it is like.
