I have an eheim 2217 that I'll be adding to my reef, (when I set it up)
Should I be putting anything in the eheim? Or use it just for water circulation, and the occasional dosage or carbon ?
Some people tell me to put a cloth/sponge, but I hear its better to leave it empty..
Thanks for your oppinions..
