Does anyone near middletown have good water test equipment?

[j80]

I have an API drip kit that shows everything is good but my corals are closing up. I took water to a LFS and they said it was good but they used the same kit i have. I use distilled water right now so that might be part of the problem because I read it's ok to use then i read it's bad to use. I just need a good reading to see if i'm reading my test's right. My sand turns brown over night and i can't get rid of it. I run GFO and have cheato in my sump.
