My DC is lime green all the time, I have moved it about a bit and it remains constant.Flyfisherman said:Blimey - mine last approx. 3 months on 215 ltr @ 4-5 bps - dc are lime green,
what colour are your dc's and do they remain a constant colour
is your surface water like the sea in a force 9 gale - this would allow all co2 within the water column to escape
or you have a leak somewhere, test all your joints with soapy water.
You are indeed correct. Normal PVC airline becomes permeable when used with CO2 so you will actually lose it through the walls of the pipe. Not sure what time scale though, but I would think it's longer than 2 weeks.Cro said:I'm just wondering now if air line will allow seapage of C02?
