No mate just standard square pond , but want to know things like how deep , how to add filters if needed where or how to fit pump and wiring ect
OK
The recommended minimum depth for a koi pond is 1m and with regards to filtration i will always recommend a bottom drain and again depending on size you may require 1 x 4 inch or several 2 inch or 4 inch bottom drains.
Here is a sketch of a set of two stock pools that i did for a friend of mine they were 5m x 3m x 2m deep both were independent from each others filtration system as he had imported koi coming in every few months, and wanted to use one as a quarantine pool and the other as a holding pool whilst he moved his stock in the shop
Notice i used 2 x 4 inch bottom drains in each pool , the reason for this was, firstly size and secondly the amount of stock he was holding in each pool , poo, unwanted food and debris all can have an impact on the quality of koi care, also on this build we didn't use a UV as the tanks were situated under a purpose built canopy and shaded from sunlight so the water did not go green,
One more thing i added an inlet for when it rained so natural water would pour through the pond on a regular basis giving a natural feel to the water for the koi.
Total build cost was £9k
The first thing i learn't was "you are not a koi keeper you are water keeper" and this is so true, a healthy water system is a happy koi system and each will complement each other .
You will need to calculate the size of your pond in volumes of water here is a handy little volume calculator
Volume Calculator and once you have done this then you can start to look for a suitable pump for your new pond, when choosing a pump say your pond volume is 10,000 liters you will need a 12,000 liter pump as you should be turning the water through the filtration system once every hour any less and you won't have the water removing toxins from it's self,
When filling a new or existing pond you should use a reverse osmosis system, koi are very sensitive to rust and other chemicals that are in ordinary tap water and can kill them, hence why we used rain water on the two tanks shown above.
Your filter is all dependant on your stocking levels, the more koi/fish the bigger your filter should be, you can never have too big a filter,
One more thing, airation, koi need to breath and if you only have a few koi in a large pond and have lots of natural oxygenating plants with a small water feature then you will be fine but if you have lots of koi then you will need to add an airator with bubbles that will help oxygenate the water.
I hope i've covered most things any more quests please feel free to ask.
