Ich-X Treatment Questions

[Lesa]

I am new to having fish and have learned a lot in past few weeks about what it takes to care for them. I have been watching a lot of the video's which are a big help, Thank you. My question is, I had already bought the fish the day I got the tank and had no clue about cycling a tank till after  I got them in there. So I went to the store and got Seachem Prime to keep in the water to bind the ammonia until the tank becomes cycled. I have added a few plants and check the water everyday. I change the water every other day about 50%. I have a lot of decoration in the tank also for Beneficial Bacteria to grow on. I added the Beneficial Bacteria Balls in there to help speed up the process. So far I haven't noticed any in there from the test. Its been about 3 weeks. I noticed today that my fish have Ich starting. I ordered the Ich-x from Aquarium Co-Op to help get rid of Ich. I read that I cant put it in the tank with the Prime. My question is what should I do? If I quite using Prime and the ammonia spikes my fish will die. I have Mollies, Tetras, and Mystery Snails in the 20 gallon tank.

Ultimate is also sulfonate based it interferes with the meds makeing them less effective
