Where to get just the CYA turbidity-type test kit?

[aquarium]

I found this one (http://www.poolmart.com/cyantest.htm), but it doesn't fill me with confidence when they can't even spell stabilizer correctly. :rolleyes:

Can someone please point me to a link to buy a decent turbidity-type test kit for CYA? (The type with the black dot.) I have the other tests covered.

Thanks,

Tom

I purchased a CYA kit made by Taylor from my local Leslie's yesterday. About $15.00, range is 30-100 ppm, black dot type.

(My CYA is off the charts high. Time to drain & fill.)
