So I need to go from my DIY filter to the pond distance about 1.5 metres (4' 6" ) at the moment it is a temporary (and ugly) white pipe while I test the filter. was contemplating a small pebble stream but then thought... about a gravel type filter or bog filter but it needs to be buried so I came up with this plan......
Gravity from existing filter to gravel one pipe with holes in runs along the bottom of a trough which is buried to just above pond level.water up flows through gravel and then to pond.
When it comes to cleaning time turn off the flow and cap the outlet to the pond, run some air through the air manifold and use a shop vac to suck up the dirty water on top of the sand and the fixed tube allows a wet vac to be pushed down to the sump for cleaning this out.
Any thoughts guys and girls
And now the questions
1. is this a real crap idea
2. was thinking of using a small kiddies sand box as a container as it is the right size (1 m x 0.8 m, 3' x 2' 8") fits nicely in the space available but not very deep. is there a minimum depth of sand and gravel for it to be effective, how much water should sit on top of the sand. dont want sand in the pond do we now.
3. Would like to grow some plants in there in the gravel veggie filter style does this mean I should get rid of the sand and if so would this be effective with just the gravel
4. am i right in thinking that sand gravel filters need cleaning but bog type filters dont.
Any help would be appreciated
Thanks
