Ich, aquarium salt, plants, and algae…

So my guppy tank has an outbreak of what looks like ICH. I’ve heard that it could be cured with aquarium salt but it’s also a planted tank with
Hornwort
Anubias
Moneywort
What looks rotala
Cryptocoryne Wendtii
How much salt can they tolerate if they can? Also to my knowledge how aquarium salt works is that it dehydrates the ich parasites and causes than to die and since the fish are more hydrated they live. Would the same principle work with plants and algae?

For the concentration of salt you'll need for ich, I'd remove your plants or your fish to a quarantine tank for a while. The ich WILL die off with no host, so if you keep your plants quarantined for about a month, you can treat your fish and keep both plants and fish healthy and safe.

Yes, it does dehydrate the plants, also stressing them and making them more susceptible to disease. For me, wendtii have been pretty tough and I've kept them in during low concentrations with no issue (so far), and anubias, well, they're somewhat indestructible so, if you keep them in my bet's on those.

 

Sorry it took me so long to answer
Thanks for the help I think I’ll use the quarantine tank then. But now a new problem has shown up one of my female guppies is no longer showing the white spots and has a sort of white fuzzy powder layer on her head and is generally not looking very happy she still eats but has gotten a lot skinnier then when I saw her last is this part of ich?
(excuse the plastic cup background I needed to make it show up better)

It could be a secondary fungal infection, is it a fuzzy carpet of sorts?, if it is I would treat with malachite green

 

Yes Would it spread? If so should i treat the others too
