green algae

I have a hard green algae growing on my tank. I have been having to use a razor to get it off of my glass as the magnetic scrubber i normally go over the glass with can’t remove it. Any ideas as to what sort of algae this could be, it is a brightish green, not like coraline Thanks

Went to bed last night and all was good with our tank. Woke up and now we had a bloom of green algae. What would cause something like this and what can be done to remedy it? We have a Red Sea light set to run at 70% White and 70% Blue for 8 hours, moon for 4 hours at 15-10%. We went off what...

Just discovered my Valentini Puffer going to town on a patch of gha on my live rock. I’m wondering do puffers usually go for that,? Maybe some copepods in there, hmmm

I'm not sure if this is bryopsis, green hair algae, or some other kind of green turf algae. It's slowly taking over my tank no matter how much I peal off. I've tried, snails, urchins, crabs, hair algae, fluco treatment. I have a algae scrubber running growing nicely and a giant skimmer...

Should I be taking any action, or just letting it ride? Tank is about 2 months post-cycle. Finally turned on the lights...I suspect I had the white lights on too long (about 8 hours), but reduced to about 3hrs at 50% with remaining time at blues. A couple days after the lights turned on, a...
