[FONT="]Hello, thanks for answering![/FONT]
[FONT="]I was planning to build it in the basement, so the water temperature will be more or less constant even though it will be heated.[/FONT]
[FONT="]First of all there is already the stone wall on which there are 2 stores of the house. Then all I will do is to build another front wall either from bricks or stone and will strengthen it with iron rods placed through the wall.[/FONT]
[FONT="]Then a layer of about 10cm thickness jablo will cover the walls thus to insulate it and then a covering of marine wood will be screwed to the jablo and the walls. Then a thick covering of fiberglass will be laid o n the wood.[/FONT]
[FONT="]Afterwards I was planning for a 15,000 liter per hour pump since I calculate that the pond will have a maximum capacity of 6000 liters. Then also I will add a small pump which will be with a timer, thus all the dirt will be carried towards the ‘big’ pump. As a filtration I am planning to use biohome….see[/FONT]

[FONT="]This site says about biohome pellets:[/FONT]
[FONT="]Recommended ratio of media to water is as follows; [/FONT]
[FONT="]Marine Environment 1 Liter Biohome = 1125 Liters of water[/FONT]
[FONT="]Freshwater 1 Liter Biohome = 2250 Liters of water[/FONT]
[FONT="]So……I will only need about 3 liters of filter media....if it is true!!![/FONT]
[FONT="]Then everything will be covered with some sort of thick plastic…so the fish will not jump out. Regarding heating I was planning for about 5 eheim/jagger heaters considering that my cold water aquarium in the basement, its temperature never falls more than 19 degrees Celsius.[/FONT]
