Okay, So I have been reading for most of the morning and I have realized I didn't quite cycle my tank properly

Like I mentioned earlier I did let it run for a little over a week with just the plants, driftwood, ETC. but I went ahead and listened to the
LFS and went ahead with stocking because they said i would be okay.
I got my water tested today and they said the ammonia was a little high and the nitrates were just a tad high aswell.
I didn't mention that for the substrate i'm using fluorite underneath the regular gravel (does that affect the cycleing in any way?) And I hav had to rely on the
LFS for water tests any ideas on where to get a good liquid test kit for myself?
