I'm looking at how to plumb the aquarium. I keep seeing this purple glue stuff that people use to seal pvc joints and such. Is this just silicone?
I have a small version of this UV that I throw on a tank every once in a while if I have cyano or ich or maybe just green water. I use it primarily on smaller tanks (the 16 I am currently setting up used to be my QT and this ran on it whenever I bought a fish...). If you do run it in the sump, then you will kill pods, though not necessarily all of them. This type of UV is freestanding, as opposed to other UVs that are hard plumbed into the return which will kill all the pods and anything else entering the display.
The purple stuff around PVC joints is primer for the glue. It is not 100% neccesary, but a lot of people like to use to ensure the glue fitting.
