This is done using Mardel 5 in 1 test strips. I tested the ammonia levels with a seperate test with the API ammonia NH3/NH4+ (that has the test tube and two solutions to test). I forgot to add that, since I have a 28 gallon tank and I'm also currently using an aquaclear 50 power filter on my tank as well. I do daily 20-25% water changes before adding more ich medicne as stated in the directions and kept my temperature up and stable as well. Today i added some aquarium salt and dissolved it in water before slowly adding it to the tank.
Nitrites at levels you posted are toxic,(deadly) and I would perform larger daily water changes while continuing the ICH medication.
Would set temp at 82 degrees F and add an airstone to help increase dissolved oxygen which is depleted at higher temps.
Would withold feedings while medicating the fish or offer very tiny amount an hour before your next water change. (if fish are eating)
In two month old cycled tank, there should be zero ammonia,and nitrites,and there should be some detectable nitrAtes. Something has in my view wiped out the biological filter if the tank was indeed cycled at some point.
In any event,a little larger daily water changes perhaps 50 percent,, will be needed until the biological filter has once more been established.
I would also purchase a water conditioner such as PRIME or AMQUEL+ both of which will detoxify ammonia,and nitrites along with chlorine and chloramines.
Would not clean or replace filter material for the next month as most of the good bacteria needed for biological filter will be found in the filter.
As long as you are getting readings above zero for ammonia and nitrites,daily water changes of fifty pecent and followed by re-dosing of ICH meds for time indicated will be needed. IMHO
