wat is teeth? Do i need it?
It has a list of extras to the side to add to the order what all do I need?
And which pump do I get with it? lol
i dont remember what size tank your using but if your using a 10g I would get the mag 5. as for the extra's just say black for the elbow and your t-shirt size. for length I would thing short is fine for a 40 BUT if your not sure you can get the long and cut it down if you have to.
As for teeth it all depends. I got teeth to keep critters from flowing over the top but you get less surface skimming with it compared to no teeth. Also with teeth its a little harder to figure out where the water line will exactly be.
