I will start to build my (2) 55 gallon biofilter this weekend and was going to go on the advice of one of the Dr's that is using the irrigation tubing (7,000 x 2 = about 4 hours straight of cutting, can't wait).
My question is, is the tubing that is being used the flexible tubing or is this like a black PVC pipe?
Thanks again for any help any of you can give me.
P.S. I thought about using the scrubbies that everyone keeps talking about, but it seems like it would cost a lot more money to purchase enough of these to fill up 2 55 gallon drums.
