so i'm in the market for some powerheads to replace my koralias. here are my questions:
1) what's the difference between the WP series and the FS series? WP25 vs FS8000 are supposedly different even though they have the same turn-over ratio.
2) is/was there an improvement from 2013 versions to 2014 versions? on fish-street.com they're claiming some changes to the powerheads were made but i was wondering if the older versions work just as well. i'm saying the "older" version because the site i'm getting the info from doesn't state whether it's a 2013 version or the "latest"(2014) version (2014 version is from fish-street)
