Hi everyone, I have a 125 gallon tank with 2 RES and my API Filstar XP4 is just not keeping the water as clear as I want it to be, it also started making a little more noise than it used to. I want to add another canister filter to my tank to increase the filtration, which is the best to get? I found this one on Amazon, http://www.amazon.com/Penn-Plax-Cascade ... ter+filter
How good would this be? I like it because it is relatively cheaper compared to the others but how well does it perform? Thanks
