Dr. thanks for the info on the koi store....... i know quite a bit about koi and ponds, had a 5000 gallon in america.......if you get a UV light and install it AFTER the filter right before the water goes into the pond it will get rid of your green water in a couple of days and keep it clear
would you recomend your contractor......I am looking for one now....if this were america i would build it myself but too much trouble over here.
thanks
feel free to PM me with any questions..............

i could recommend the contractor any day. actually he has built my pool as a subcontractor and was only willing to build my pond after i pressed him to do so. of course the pond was expensive but it was built pool-like with concrete and steel reinforcements which justifies the price. using thinner walls and bottom as well as reducing steel diameters would definitely bring the price down quite a bit. what i don't know is whether he takes on a smaller job like a 5.000 gallon pond. mine is around 105m3 = ~ 28.000 gallons. another problem is his lack of english. you would have to go through the general contractor who built my home. i will PM you with his name and phone-number.
"UV": i was thinking already of all kinds of solutions. the biggest problem is that the pond is obviously too big for normal filtration. i can't run the filter pump longer than 2 hours till the algae is blocking the filter completely. installing UV is another headache although there is not too much head pressure on the outlet (waterfall).
perhaps we should get together (i am living 10 minutes away from Jomtien) and exchange views over a beer or a glass of wine? exchanging views on constructing a pond of course. as far as kois are concerned i am a bloody newbie and would like to get advice from somebody like you who has relevant experience.
Hi there
I have some advice for you for building a koi pond.
You do it ones , but do it good , one's built it is going to be very difficult to change anything ,and a small mistake your pond will not work ,you need to understand the difference between a pond and a koi pond .
you should make it as deep as possible , but minimum 1.5 meter or 5 feet deep , if not the watertemp will change to much which will stress the fish , and can make them sick also they need to be able to swim from up to down to maintain a good body shape, second and most importend off all you should make bottum drains off 4 inch minimum (for gravite vet filtration),on the deepest point off your pond , minimum 1 for every 25 cbm , and third, standard size here in thailand for filtration is 30 procent off your pond size , so if your pond is 10 cbm your filter should be 5 cbm , NOTE a filter can only be to small , never to big. there are are some good koi filters for sale in bangkok , smaller but expensive ( nexus and answer )
And last If you built a filter , make sure that you design one also with bottom drains for easy cleaning , a typical koi pond filter is a vortex and 3 or 4 chamber filtration ,1 mechanical , and 2 bio chambers and 1 chamber with oystershell and or zeonite
Do not forget kois grow FAST when the water is warm , and eat a lot , so your pond will be quickly overstocked,
So all with all a good pond will cost a lot , but will bring you pleasure for a long time , a badly built pond will just bring you headache and waste off money.
good luck Willem ( if you need more advice you can mail me)
