Please help!

[Nuttygal! :0)]

In one of my tanks, a 10gal, I have three young platys (2 high-fin and 1 sunset) and a lovely male betta. They are fairly new, and a minute ago I realised one of the platys has fungus and/finrot. I have moved her to a 5gal hospital tank. I added the last few drops of Protozin that I have, and I don't have any more medicines. I have normal table salt ~ but I don't think I can use that because it has baking soda or something doesn't it? ~ But I have normal sea salt. The ingredients are...
sea salt
anticaking agent
magnesium carbonate
potassium hexacyanoferrate ll.
Could I do salt dips in this until I can get to a LFS tomorrow? And should I treat my 10gal?



Plz help me.

Use some meds, they are much safer on fry than salts and other baths; just out of curiosity, why do you have a betta in a fry tank?? bettas eat fry!

They're not exactly fry! They're not very far off from being full grown, but they're not too big at the moment.
Thanks for the links, Wilder.

Whoops sorry, thought you said fry "doh!"
Good luck with treating them

Thanks everyone. I was having a panick attack but have calmed down now.
OK, I have added the sea salt (Only a few grains) to each tank. At first the betta flared out his front fins and took a H-U-G-E breath, and I thought OMG what have I done! I've killed him! But they're ok now. But my little snail Speedy is floating at the top.
Fingers crossed everything will be ok!

EDIT: OMG I just remembered! SALT KILLS SNAILS! Oh no I've killed him!

I was just going to say can you remove the snail out of the tank, how is he.
