Ich and Ammonia spike

[ToothlessTheGuppy]

Hello everyone!
A few weeks ago, I started my first aquarium in 10 years. I moved some plants, snails, nitrifying bacteria (neo V, aquario), and finally, some fish - 5 guppies. Unfortunately, one of them developed ich. They were all from the same tank from the same shop. So I treated my aquarium with medication I got from my local fish shop and turn up the heater. But now, another problem has arisen. The ammonia level is higher than before - 0.05 ppm. I think it's probably because the medication killed all the beneficial bacteria. 😞 The medication contains brilliant green hydrochloride - 1 mg and malachite green hydrochloride - 4 mg. What should I do? If I dose another portion of bacteria, they'll probably die as well...

I’m sorry you are having difficulty. 
water changes and an ammonia neutralizing dechlorinator like Fritz, Prime or AmQuel are what I find most helpful in these situations. Here is an article you may find helpful in understanding how those chemicals can assist. 
Temperature may also be playing a role. Different bacteria strains thrive at different temperatures. When a particular bacteria reaches the edge limits of it ideal temperature it can struggle or die off.

Thank you for your answer! I'll try it and I'll get familiar with the article. 🙂
