On my 125g tank I have a sump that has pvc tubing and not normal flexible tubing. I have done some research about co2 in large tanks and most people say an inline diffuser is the best option, but I have pvc piping. Are there inline co2 diffusers that can go on pvc? If not what is my next best option for co2 diffusion?
