The FPI C50 is designed for a 1 hp pump. Bigger wont filter properly, it will bypass as I recall it.

I worked for FPI. This filter was originally designed to match their 1 hp at the time.You really can't go by the HP of the pump to determine if it is suitable for a particular filter.
thanks, also on the pump usage, i think to maintain temperature will need to run both the heater and the pump more often then just that. so in the long term it may pay off getting a pump under 1hp. for now im going to test 1.25hp later this evening...Fittings are usually rated just as high as pipe.
How much do you really use the spa where power usage is even a consideration?
How long do you run the pump each day? Shouldn't need more than 30 min for just circulation and filtering.
It should be fine. Those are med head med flow pumps.
It is not matched to any pump larger. Generally, 1 hp pumps will all flow similarly within physical limits. It won't matter enough to justify a different filter whether the pump does 167 or 197 lpm on a domestic setting. Sorry for using ROT for this, but it's too long back to be specific.While it might have been matched to their 1 HP pump, it does not mean it will work for every 1 HP pump nor does it mean it will not work for a pump that is larger. The operating point of the pump matters.
There can be a very LARGE difference between pumps with the same HP rating. While there is some correlation between a motor HP rating and the attached pump's head curve, you really cannot deduce one from other.It is not matched to any pump larger.

does it mean that above 1hp generally is not recommended. or if unsure, beterr go slightly less ie .75hp? though 1.25hp should not provide too much more pressure i would hope so. The Badu Spec Super 90/350 has 350l/m flow and has been removed from a similar old inground spa togehter with the other FPI filter so this suggests it should be ok..It is not matched to any pump larger.

Badu spec is not a good match. These are a later model pump with a large flow model. I would be looking for a flow of about 150-200 lpm and no higher at about 6 metres on the pump curve.does it mean that above 1hp generally is not recommended. or if unsure, beterr go slightly less ie .75hp? though 1.25hp should not provide too much more pressure i would hope so.
