I got a CO2 diffuser unit that looks like a long cylinder with bio-balls inside. The intake and output nozzles are at each end. I boought some tubing and a clamp at Home Depot so that I could connect the output tube from my Eheim filter to the intake tube of the CO2 diffuser. I am having a hard time getting a water proof connection at the intake connector of the Eheim filter. Has anyone else had this problem? The tubing for the filter looks slightly different from the tubing I bought at Home Depot. There must be a simple solution. --B ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
