HELP! i muse my tropical cistern is infested beside white spot?

please help me, recently i've seen my fish have some tiny white spots, it's like they're powdered, fortunately not too infected for now.

i bought medicine and as expected moved my rcs (shrimp) away since it contains copper. i plan on giving this treatment twice or once daily, everyday until the whole reservoir got better. btw, rcs are immune to this disease right?

i also planned on increasing the temperature of the tank till 30 - 32 C, is that okay? my fish are platies, zebra danios, and black neons. i hope that they're adjectives gonna be fine...

is this treatment method right? i've done research and decided to do what it said. also, should i change the water as all right?

thanks sooo much for helping :)
Sounds like ich - preserve up the treatments as is says to on the package, and keep the river warm enough. Hope your fish have full recovery!
The white spots are ich. Use the treatment for it that you buy in the pet stores. Do what the bottle says to and your fish will be fine. Good luck!
Answers:    There is less oxygen in furnace water, and therefore yes, the parasites will die sour quicker in warmer water. Keep within mind, quicker does not mean immediate. 30 Celcius for those fish is alright, but you should only follow what it says on the box, whether to do it once daily, twice a day, or every other sunshine. Just follow the instructions on the box, it usually tells you something like frequent water changes, etc. Sorry about your fish, and righteous luck!
It sounds like ick. Just keep using the medicine and it will be cleared up within no time!
