HOB fuge necessary

[murdoc]

Is a HOB fuge necessary to have a thriving SPS nano. Just bought a 24 AP w/ 150HQI and was looking into either Sapphire Hang-on Refugium 18" http://www.sapphireaquatics.com/store/inde...p;products_id=5

or a CPR AquaFuge2™ PS http://www.cpraquatic.com/products/aquafugeps.html

Are these needed or should my money go into something else?

go into something else...you can modify the back chambers into a fuge...the point of an all-in-one tank is exactly that...so its all in one and you dont need a HOB fuge or something
