Hi,
Thought I would post as I have learnt so much from lurking around this and other forums.
This was all prompted by removing alot of silt from the bottom of the pond and trying to clear the green water problems. The Bioforce submerged filter is really CR@P and would need cleaning twice a week if you are considering buying one of these dont, it could never cope with the pond even when there were less fish, in the winter. absolute rubbish really fiddly to clean and maintain.
Pond is approx 4500 litres with lots of fish, dunno how many cant see to count them(Ghost Koi, goldfish, Orfe and Rudd) they were all small when we bought them 5 years ago and plants.
The filter is a vortex (though I am not sure I actually get much Vortex action) in a large plant pot, inlet pipe is 22 mm overflow pipe which has been bent round the pot and exits from two elbows, there is a bath waste and I splashed out on a slide valve to drain the outer chamber. Following this I have used scourers as a mechanical filter (more needed) then the biological part is the media from my Hozelock Bioforce 4500 filter with added homemade media. Plastic plumbing pipe cut into 1" sections (hey its cheap i.e. free offcuts)
So I am after some comments it is currently running after the Bioforce only been going a few days and it needs more mechanical filtration, while I fiddle and tweak things, could have made the water flow better through the bio media as at the moment it enters the top of the inner pot and straight through the outlet. Is it enough that the media is just in the water or do I need a proper flow through the media? if I change the outlet elbow so it draws water from the bottom of the inner pot would this help.
Am thinking of a homemade venturi to help the bio media along but am not sure i get the flow rate required. May try a cheapie air pump and stone.
Still have to add an overflow to the main pot and adjust the standpipe in the inside pot as it is used as an overflow and also when filling.
the outlet to the pond is temporary till I build a little stream but the water draws alot of air down the outlet tube with it and the fish seem instantly grateful.
Possible Future improvements? some form of fine sieve on the outlet, but it must be easy to clean.
Venturi ?
Air Pump ?
Any comments Guys and girls
will try to post some pics
