[QUOTE=gSTiTcH;3211009]I find that pressurized is more cost effective and safe, so long as you take the right precautions when handling the tank, etc. Sugar gets expensive. Also, what is your time worth? The less I'm mucking with CO2 mixtures, the more time I have to take care of other things in and out of the tank.QUOTE]
+1. For small tank, DIY is ok. but for larger tanks, its a pain mixing yeast and sugar every week. If you run high light to bring the colors of plants, DIY always ends up with algae because of fluctuations.
