I went to my local Lowes today and looked at the filter housings they had. One of them was a "heavy duty filter" that was the standard 10" long but had a larger diameter. The housing was probably 7-8" diameter compared to the normal 4-5".

Has anyone run one of the larger diameter versions? Going from 5" to 7" diameter almost doubles the cross sectional area. So for any particular pump flow rate the speed of the water column in the reactor would also be halved. That should help with bubbles escaping, contact time, and maybe even noise right?

Only downside is it was $63 for the clear version (3/4" fittings).
