I was wondering if anyone has had any exp with the CPR BAK_PAK skimmers I am thinking about maybe getting one. Or if anyone has some advice on a good hang on back for a 29 gallon tank thanks

I had an Aqua c Remora on my 29 and I thought it did a very good job.

I have a Remora on my nano. I'm plenty happy with it as well.

I am currently using the Remora on my bowfront too. I do like it, and it is very comparible to the CPR product.

I did use a CPR BakPak II on my first tank, a 20 gallon LPS Softie reef:

It worked amazingly well and is very easy to clean/maintain. I guess what I'm saying is ... "either or" in my book. They are not Seaclones ;)
