im making a new system dedicated purely to providing water circulation and co2 to my tank . im going to be using a 1200lph powerhead plumbed into a tmc aquagro 1500 co2 reactor ( external) , and back into the tank via a full length spraybar ( 12mm acrylic tube) . length of spraybar will be 80cm . i was thinking of initially going with a 2mm hole every 50 to 60mm , simply because the holes in my eheim spraybar are about that size/spacing . am i on the right lines , or do i need to be using some mathematical formula to arrive at the best hole size/spacing based on the length of spraybar and flowrate of the pump feeding it ?
