Yeup I just finished doing my
DIY C02 set up... Basically a 2 liter with hose running into the top of my aquaclear 70 into an airstone.. The idea is simple...
1) Create C02 using yeast and sugar...
2) Pressurized C02 will go through the hose and into the air stone which is located inside the inlet side of the aqua clear 70
3) When the air stone releases the small bubbles of C02 the inlet impeller will grab them and mash them into bits
4) The smaller C02 bubbles will travel through the mechanical, chemical, and biological filter beds and be dissolved into the outgoing water stream
So that is the idea... Now I need to figure out how to see if it is working or not.. LOL!!
