Algae ID, H202 and High Mag question

[TheSaint216]

Well I think I miss Identified an Algae problem thinking it was Bryopsis. I elevated my Mag up to 1800 with Kent Tech M and did a lights out for three days, Turned lights back on and poof it was gone. Well with the lights coming back on the Algae started to come back. I read something today that made me rethink that I really had dinoflagellates. A couple things I have read is the lights out totally getting rid of it. I dipped some Zoas last night in Hydrogen peroxide to get rid of some hair algae and what looks like dinoflagellates. The Dino totally dissappeared using a 60 to 40 Water to peroxide mix. I enclosed a pic below so you can tell me what you feel it is. Its long and stringy, sometimes has bubbles in it. Ive read H202 dosing in the tank of 1ml to every 10 gallons can kill this stuff off. My question is would you attempt this with such an elevated MAG? Thoughts?

All you needed to do was adjust you lighting so the algae would stay away.
Obviously you have two datums. no light no algae. and light with algae.

someplace in between the two would allow the thank to thrive and the algae stay away.

is it derbesia (hair algae)? I think lowering phosphates would be key
