test kits

Are there any test kits that will test for FC above 5ppm? Right now I am using a Taylor DPD kit.

Do a search for shot glass method :)

any FAS-DPD titration test such as Taylor K-2006 or Ben's ps234 will do it. If you are using a DPD colormetric test (match up the colors) you can dilute the sample and multiply the reading by the dilution factor.
