If that's the case, just order some extra R-0871, R-0870 and maybe R-0003 (but you probably don't need this one yet) from TFTestkits.net.

Here's the page with the XL option. That should take care of you for the time being.

Remember, when you get the kit it will say to use 25ml of pool water for your FC testing. Don't do that. 10 ml works perfectly fine for your purposes and each drop equals .5ppm.
