This drawing is a bit rough. The CO2 chamber should be the same size as the filter, but you can see the principle.
Water comes in thrugh the grid in the back wall, and is cleaned. Its pumped out in the top thrugh the outlet pipe, where the CO2 is injected. Hopefully this way i can dissolve the CO2. The holes in the outletpipe is directed towards the bottom/opposite side of the tank.
I wondered over how to clean the CO2 chamber - (Thanks Sietch) and dicided that a cap in the bottom would be the solution... That way i can just move the tank over my sink, and rinse the chamber with water...
The volume of the CO2/Filter-chamber issent desided yet, since i dont have the pump yet... But approx. 1/4 gal.
So 1/4 gal CO2 chamber - with 3,4 fluid ounce of sugar, 1 tsp of baking soda, 1 tsp yeast and 25 fluid ounce of water... This should give more than enugh CO2 for it to last 2 weeks...
Im ordering the polycarbonate this weekend, and hopefully ill will get it next week.
I havent figured out how to glue/silicone it together, but ill try and find the best way, and already got some good advice from scolleys tread
Im probally cutting it with a saw, and then grind and polish the cuts.
But im going to do some testing before making the tank...
More questions please... There great help!
