I have a 29-gallon saltwater tank with just a few live corals in it. I guess I have a diatom film all over my coral. Is that bad? Also, one of my coral has turned from green to yellow. I bought 5 coral and I'd say 4 lived. One died but I see numerous "sprouts" all around it. I'm cautious not to add fish until the coral looks more accumulated. Question do I run just blue light only to help the corals grow?
Had a 50 gal many years past. Getting back into the hobby.

There's no way to no way to answer your question. Can you please provide specific info about your tank?
How old?
Cycled properly?
All water parameters
Picture would definitely help
Light fixture....

In addition to this, could you post some pictures, especially of the corals.
