As the title states Would you recommend the Rena Filstar xp4? I am setting up a 150 gallon grow out tank for rays and I want to have perfect filtration, I already have a cascade 1200 canister that is rated for a 150 gallon tank and I am very happy with the performance of that filter. I want to add an extra filter, I'm looking at the xp4 which is rated for tanks up to 260 gallons, this filter would filter my 150 gallon tank along with the cascade 1200 canister. Please let me know if you recommend the xp4 or not. Thanks
