so just recently I noticed this growing on my sand and rocks and I have had 20 gallon up for about 2 months now and I run my is primes daily at 10% about on acclimation mode , my LFS said to try a Rabbit fish??? or a sea urchin im worried a sea urchin will knock my rocks over what is my best bet to get it to stop growing could my lighting be causing the issue

Bryopsis is a heck of a pest. I was able to kill it recently with a few rounds of hydrogen peroxide dips. Very few things will kill/eat it, so good luck and stay on top of it before it gets really bad.

what is my best option so I can star tonight and what likely started it ???

Bryopsis can come in on anything from another infested tank, usually a rock, frag plug, etc.

A 60-second dip in the 3% hydrogen peroxide from your local pharmacy will kill it, although sometimes it can take multiple treatments. The peroxide will also hurt or kill any invert/corals, so be careful about it and rinse everything in used tank water before putting it back. The bryopsis should turn white and die in 2-3 days after the dip.

I would do peroxide and a 3 day black out.

I would scoop it out (photo you provided) with the biggest spoon you have to hand and discard, anything you can remove manually will prevent any further infestation, I would turn of all filters pumps etc to stop flow in aquriam and remove it
