Just replied after reading one of your posts about your xp3 figure I'll post my question here as well.
I see you have XP4 and Rena XP3 on your 90G I was planning either 2 XP3 or one of each on my 180G do you think this is enough filtration? I plan to add some additional current with a powerhead. How do you like the Rena filters?
