Maxi-jet 900 or 1200?


Active Member
I have a CPR Bak Pak 2 with a Maxi-jet 900. I purchased the 900 because it is similar in gph to the Rio 600 that it came with. However, others upgrade to a 1200. Is that really necessary? I only have a 30 gallon high tank, and I don't want too much current. I have 2 other 900s providing the current in the tank already.
