Livebearer tank/Ich/Salt question

[Jonatheber]

I may have some ich in my tank. Some white raised spots showed up on two of my three Painted Glass tetras. I see NO signs of spots anywhere else. I also have a golden algae eater, a bunch of guppies and a few platys and mollys. As a preventative measure, I added aquarium salt - 1 TBS/3 gallons (46 gallon tank, 16 or so tablespoons).


1) Is that the right ratio for preventative measures? I'm not convinced I have it - I don't see ANY spots on any other fish.
2) I have a bunch of guppy babies. Is that concentration likely to harm the babies that are obviously much smaller?

Below are a couple articles for Ich.

Get the water quality in A1 condition.

Glass fish are more sensitive to issues with water quality. Also if they are injected dyed, they will be possibly more delicate as well.

What are your water parameters?

How long has the tank been set up?

Are you familiar with the nitrification cycle? The article in the bottom in my signature also gives you lots of helps, understanding and knowing important things for a successful aquarium.
