I am feeling very discouraged right now and I wonder if anyone here has any advice. I started treating for Ich a couple days ago because my Platies have been scratching against ornaments and plants for a few weeks. One, in particular has clamped fins and has been hiding a lot. I tried to take the conservative route and simply focus on clean, stable water conditions (which I achieved), but the itching and reclusive behavior continued, so I finally opted to treat the tank. I added air stones and started slowly increasing heat over the last couple days. I also took out the carbon filter media and started adding a product called Ich Attack, which is supposed to be snail and plant safe, along with a very low dose of aquarium salt. The temperature rose from 75 to 81-degrees over a 48 hour period and I found one of my platies dead this morning. The other one is really subdued and I will be surprised if she makes it through the night. The whole thing has been devastating and I feel I am not destined to keep platies. They are my favorite fish, but it is heartbreaking to lose them.
Obviously, I won't increase temperature any further. I did do a water change today, but I'm not sure if I should completely stop treatment or not. If there is a parasite, I'd like to get rid of it, but don't want to lose all my fish.

I realize the nitrate reading doesn't make sense for a cycled tank, but it has been set up with fish since early July.
