I'm building a 5metre x 3metre indoor pond and having a 1 metre wide channel all the way down the outside (5x1m). The channel will become my filter - split into 5 sections. I would love to have it all done in fibreglass, but finances say it has to be a liner for now. The main pond will be a box-welded liner to fit, the channel/filter I thought I'd just make from a sheet.
4 inch feed near the bottom of the main pond into the filter, with an 90 degree elbow taking the water upwards and then split into 4 to create a whirlpool effect. Over the first chamber, into the second, under into the 3rd etc. Then pumped out from the last chamber.
I guess having a pond liner in the channel will mean I'll have to separate the sections with plastic. Any one have any experience of this? I'm thinking plastic sheets pressing against the sides of the channel. Possibly with a liner over the plastic pieces to help protect from piercing.
The alternative is to leave the channel until I can afford to have it made from fibreglass to my exact specification and use an external system.
Am I missing anything glaringly obvious? (it wouldn't be the first time)
