"I Just got my Rena Filstar Xp2 few days ago, I installed yesterday. The setup is easy, but the plumbing part is a little confuse. You will know if you are going to buy it. But I don't recommend it at all. After I set it up and run it, the filter was very very loud, trust me, you can't sleep with that in your bedroom. The second problem is that this filstar xp2 filter doesn't work well with a 29 gallon saltwater tank, I run it overnight, I Hardly see any different in the water, it is still cloudy. I am very disappointted with all the good reviews I have read before I bought this filter. they are just not true."
