IMO I wouldnt use a CL on a smaller tank. Its just a pain to drill all the hole and taking a chance with thin glass. Also If I were to have a CL I would want to be able to drill the bottom..... Good luck finding a tank without a tempered bottom. A CL is also a pain when it come to aquascaping. If the tank was going to be Large and Inwall I could see using a CL, but on this setup I think you will be happy with the wavebox and a couple powerheads.JMO. Also if you look at alot of CL tanks you will find they are using PH's, wavebox's, and vortechs......
