Too much current?

[Canadian Man]

Well i will explaine first. i had a rio 2100 pump on the right side of my 90g tank and 3 other small ph's on the left side. i purchased a rio 1700 pump to replace the many ph's on the left side of the tank. i put both rio's on spraybars going across the tank and had a sand storm so i took them off and just used the adjustable outputs. no sand storm but i have a heck of alot of current in my tank now and i am wondering if it is too much? i know rio's suck so i dont want to hear about that but in case you dont know their gph's the 2100 is 690 gph and the 1700 is 640 gph so a total of 1330 gph not including my output from my 404 and seaclone skimmer. so what do you think.
the tank is a mixture of softies, lps and sps(well only one sps and monti)
thanks for your reply's in advance.
cheers
Jonathan.
