I keep snails to keep the diatoms and detritus off the leaves. Snails get a pretty bad rap but quite unfairly..if you're having algae problems on the leaves I'd try some ramshorn, pond, or bladder snails. None of these snails will overpopulate unless you're overfeeding, and they're all easy to remove by hand if you need to.
It could be the plants melted from the direct change of tank. Even with the same lighting, you'll have a difference in depth, which affects the amount of light that reaches the leaves. The wattage is less important than how much actual light reaches the leaves, which depends on the height of the tank, how far the lights are from the top of the tank itself, the wattage, and in some cases the color temp (but color temp is more about us enjoying the light, as the plants can grow in a much wider color temp than most of us use).
From what I understand, you're saying that you moved all the plants to the new tank right? If you exposed the roots, or there was a temperature or ph shock that can cause the plants to melt. If this the same tank that has 0 nitrates?
Sorry, went to eat dinner.
Hydrogen peroxide is used for killing BBA. It actually can kill the plants leaves if you leave it in the dip too long, but usually it's pretty harmless to them. You can use a syringe to squirt problem areas on plants you can't take out to dip, as hydrogen peroxide is harmless in its broken down form and it basically just turns into water.
