You can put the output tube of your DIY CO2 directly beside the input tube of your Dolphin f1200. In that way, eventhough you do not have a ceramic diffuser, your wall filter will act as a CO2 reactor at the same time your filter. The problem with CO2 is it has higher density than ordinary oxegyn so diffusing with ordinary airstone is not very effective. A diffuser made of ceramic would do the work perfectly. It would help if you use your airstone and put it beside the input pipe of your HOB to further break your bubbles before it enters your filter.Have fun
