Thanks all! to answer questions:
The red plant in the back is in fact hygro kompakt! When it was under my t5s in another tank, they were always emerald green. But now under 2 different led setups (lowes par38 and now my diy led) they turn a crimson red. I do dose iron, but they are that red regardless of iron dosing.
The airplants are in fact bromeliads. They cannot be submerged. the roots can't even touch the water. The branch the are attached to just rests in the tank, so once a week, I remove that branch, dunk the plants under water for a few seconds and then place the branch back where it goes. I'm already seeing a new shoot on the highest B. so the method is working.
