Eheim 2227 and PH
I use an API test kit. I always rinse them in aquarium water first including the caps. I have only gotten the big of a drop once, but with a couple of water changes it appears to be coming back up. The reason I thought it was the filter was because I heard wet/drys were nitrate factories. This filter I bought used and was used for a reef tank, but I washed the substrate and ran it on an empty 55 gallon for a week and I would change 100% of the water every other day. All my tanks vary between 0-5ppm for nitrates. Ammonia and nitrites are usually stable. I do water changes 10-20% about every 3-4 days and vac once a week.
