Algae Growing on sides?

[WalkerH]

Hello, I know it’s hard to see, but I have these little plants or algae or whatever they are growing on the glass in my salt water tank. Are they bad? Should I evict them? Or are they good for the tank? I honestly have no idea so someone please let me know. Thanks.

Algae on glass is generally removed by snails or when the aquarists does regularly scheduled glass scraping. It might be interesting to see what it turns into when you let one grow. Scrape the rest off when you clean the glass.
