Hi,
I have been running a salt water tank for a few years now and now I have a friend who is giving me a brand new 90 gallon tank. I want to make it a salt water tank, but every aquarium store gives me different answers as to what kind of filters are really necessary. I think they are basically trying to sell me whatever is most expensive.
So basically my question is, for this size tank, do I need to get a canister filter? Can I simply use a bio wheel tank top filter? Do I need a protein skimmer if I am going to put a reef system in there?
What would you suggest for starting a new 90 gallon salt water tank.
Thanks
