I was doing some water testing to see if my Nitrates are in the the correct range. First off I had a local Fish store test my water with and they said I had 0 nitrites and Nitrates with a MArdel 5 in 1 test kit. I came home and rested my water with a Red Sea Kit for Nitrate and got a reading between 5.0-10. So did anyone ever experience this with test kits?

All the time! Test kits are really wacky, and inacurrate. They older they are, the more off they get. People even report using two, brand new test kits and getting very different results. Most of us do not acutally test for this reason.
There is a sticky at the top of this forum about how to calibrate your test kit. Suggest you read it.
