Ok, almost finished put have a nice record of the process. The pond is in Midrand, on a small holding, we have borehole water, and lots of space.

Pond consists of a top, small pond, about 30cm deep, planted and stocked with some tilapia and 4 gold fish, as well as a bull frog. It has water lillies, yellow and white. Looking for red and blue (in case somebody has for sale). Total volume around 2500l.

The bottom pond, is around 45000l and is build from bricks with a coincrete filled cavity. We have 3 bottom drains, and 3 filter chambers, that are emptied by 2x .75kW pumps. One pumps returns water to the top pond, to cascade back via the waterfall.
The second pump, goes via a E-Clear UV clarifier, back into the pond.
The filter boxes will use filter material filter media from Trebo Plastics.

Both ponds are sealed with Corporox carcoal, and the top pond has been running for about 14 months now. Work that still needs to be done:

- Finsih the floor waterproofing in the big pond
- Clean the bottom drains
- Fit piping for airation
- run cable from main house
- And fit covers over the filters (not happy there yet, used Nutec boards on a welded frame) Nutec is not stablke enough.

Hoping to complete this to put water in this weekend.

And it all sort of started here:

The frames are welded, but my idea of Nutec board is not working, need to find soemthing else to use as cover.

Looking good Adi. A wooden cover for filters should look great with the tiles

What type of Tilapia do you have ... reason I ask is your design will definitely allow lots of the tilapia to end up in your koi pond.

Wanted to finish the pond today. Had two challenges:

From the building the was concrete in the bottom drains, sorted.....
and its raining, can sort that so given up for today, will try angain tomorrow

To be realistic water next weekend, sniff

On the tilapia question, they are the blue variaty, they share that pond with some yellow fish and carp.

The intenstion is also to keep some yellow fish and big big carp with the koi at the bottom. Have 3 carp that are close to 8 kg each, that need to be transferred soonest....

Ok, we are ready, yesterday we finished applying all teh Corprox, all done! Package says allow to dry for 24hours, and yes we had no rain.

Electricity is connected, only work to be done is screwing the filter covers into place. I ended up using marine ply that was painted.

Then only other activity still missing is cleaning the filter chambers (all three) and then packing the filter media in. Should be able to start filling on Saturday morning......

The most exciting part.

After a hectoc weekend, Saturday was spent doing minor small fixes in the pond on the filters. Sunday morning saw a clean, and then "WATER". Started filling at 11h00 and stopped at about 21h00 that night. Resumed Monday after work, found a small leak between the filter chambers 1 and 2 where the pipes connect. Fixed that last night, with a home made plan. Used Coprox water proofing, they also have a waterproof crack filler. If you mix teh crack filler and the water proofing to a sludge, you get a sludgy waterproof crack filler, that hopefully did the trick. Resumed filling water this morning, about 50cm still missing hoping to put that in night.

Are you measuring the volume of water you are adding?

Have borehole water and in order not to strain the pump to much, been having it on and off periodically.
Did the calculation previously, expection 48000l.......

It is really a lovely pond, nice size, and very neat. Would love to see it after the final touches, plants and fish. Well done!

Are you going to put netting over?

Busy phoning for net:
- have a 3 year old daughter
- lots of hungry Midrand birds

Does anybody have any suggestions / recommendations for a net person / place?

The best place is Alnet, who supply about 90% of all outlets, but they do sell to the public. [You must be registered and logged in to see this link.]

Branches in Midrand, Cape Town(Epping), Durban and PE

phoning them quick
