High Or Low Volume Filter Housing?

[Steelydanh]

Well, I've determined that my filter housing is kaput......the check valve spring in the bottom is is broken. Can't find a replacement part (thought it was a DynaFlo...but it's not.) and probably couldn't replace the valve anyway based on the location. Anyway, I'm gonna go ahead and change the entire housing out. Fortunately, easily accessible...and I found the cost is less than $80 bucks. Dynaflo makes 2 types of filter housings available in the size I need; a "high volume" 15 gal per minute, and a "low volume" 8 gal per minute. How do I decide which filter "volume" I need? Is one better than the other. Does it have any affect on jet pressure, etc?Thanks.
