sand filters?

[cbfreder]

That's a good question.....for a fluidized bed filter how big of a pump DO you need to run it? They never give you any idea when you look at them at the LFS or online.

Like 150 GPH for the 300 and 600 and like 175 for the 900. The manual tells you all the parts that it comes with and misc. facts: http://www.pentairaquatics.com/pdfs/R270246_fluidize_bed.pdf
