Ich and fin rot

[pxcn24]

I’m currently using API Super Cure Ick at half the recommended dose (I have 3 Mystery snails), and noticed my black molly (i also have 4 tetras, and 3 danio in 30 gal) is also showing signs of a possible secondary infection with fin rot. I only noticed these symptoms on my molly, most likely because of the dark coloring but I treated the entire aquarium. I bought API Furan-2, but I’m a little hesitant and confused on how to administer it while I’m treating for the ich, because A) I don’t know if combining the two medications will have a negative interaction B) I don’t know whether it will halt the treatment, or interfere with killing the flukes, and B) how it will effect my snails. Any advice will be greatly appreciated..thank you and have a nice day or night :)

Some photos will help. Sounds like a bacterial issue going on and treatment would be Maracyn 2. Assure to do a water change before and after treatment.
