Could use some improvement
August 16, 2014

This system uses a noisy single outlet aquarium pump (they normally sell for about $15.00) and a small cheap looking directional flow air filter that was attached backwards when I got it. Rather than using it as suggested in picture, I ended up fabricating one of the orange carboy siphon caps so that I had dual air inlet and blow off tube capping the carboy at the same time. The air feeder line on the outlet side of the filter only allows the aeration stone to go about 1/3 of the way down a carboy, whereas I assume it would be much better to have it near the bottom. You have to connect the airlines by sliding them over the airfilter outlets, a rather fussy procedure that improves your chances of contaminating the line when it is ingressing through your carboy cap before you get it sanitized properly. Overall you could build a much better system for less money if you can find an apppropriate air filter and food grade lines for it that you can attach to a better quality aquarium pump.
