I have a 55 gallon tank. Its been set up with fish in it for about 4 months. The filter is an Aqua-Tech 30-60 that came with
Your filter may need a little help. If you could afford add another, that would be good. A suggestion might be a AquaClear 70.
Run them both. Alternate weeks cleaning them.
But before you add a filter I'd suggest a better test kit, or at least take a sample of your tank and tap water into a reputable lfs for testing.

the kit I bought at the store. I dont know about the ammonia level because I use Jungle brand 5 tests in 1 test strips which only tell you the nitrate,nitrite,total hardness,total alkalinity,and ph .
A suggestion here would be a test kit with reagents and test tubes rather than the strips. There are several brands.
API (Aquarium Pharm.) makes a good master kit and you can get the GH/KH mini tests to complement it ($30 well spent)
You may be getting a false reading with the strips plus it's good to have the whole picture:
ammonia, nitrite, and nitrate.
Total hardness = GH and total alkalinity = KH.
KH is important to know when dealing with pH.
