Thanks! Also, where did you get that prefilter? I need to get one for the shrimp tank I am going to be starting up.
I got that from evilbay from a seller named e-shop37. They have 12mm, 14mm, and 16mm prefilters available. It was only around $9 bucks or so shipped, but the downside is it takes a few weeks to get from China.
Fits the above mentioned lily pipes perfect though!
