What would happen if you put a larger pump on skimmer?

[cam78]

I have a skimmer that calls for a 800 GPH hour pump. I have a brand new pump that does 900 GPH. Is that a problem? Its actually called a Henri Studios pump. Any one ever hear of it? When I bought an overflow kit online the company stated it is the best unknown pump company

assuming its a skimmer type that doesn't require matching, just a minimum/maximum pressure pump the diference is not significant.a little more would probably work better and depending on the pump it may put out more or less than one rated at 800gph. these type of skimmers would include down drafts, aquaC spray nozzle, becketts or any real venturi skimmer (real meaning air aspirated AFTER the water pump ex: elos, bermuda). needle/pin wheel skimmers or any that aspirate before the pump need to be matched well and water gph doesn't really help (you need the water they push while aspirating air).
