I have 2 blue chromis and 2 pajama cardinals that all had visible white spot as well but have survived it has now gone from their skin and they now seem fine. I upped my temperature to 30 deg c and have kept them fed and done water changes. This has all happened over the last month. I haven't used any chemicals as I have crabs and sea stars too so don't want to hurt them. My questions are how long do I keep the temp raised and when could I start to restock.
Thanks in advance for any help

Raising the temp only serves to speed up the life cycle of the parasite to better facilitate a rapid "cure" when medicating. If you are not medicating the tank then you are risking an even bigger outbreak within days.
When you see cysts on the fish, that is the adult stage, when they drop off that means they have released their progeny into the water column and have completed the life cycle. It is only when the parasite spawn are free swimming in the water column that medications work, hence raising temps to speed up the process.
My suggestion is to quarantine the remaining fish and treat them, then not return them to the main tank for at least 6-8 weeks, preferably 10 to allow the parasites to die off without any hosts in the tank.
