Personally I always had problems. I wish bryopsis would just go away. Unfortunately it doesn't work that way. Same goes for a few other things unless you use a treatment. For the most part take the veteran advice or some noobs advice that have talked to veterans of the hobby. Find stability for your tank. Let it pan out. If you want to achieve different goals. They will most likely require some extra care like a dragonet or SPS. It's not technically a problem if you have the right ecosystem for it. I 100% agree and with experience also having gone through diatoms, algaes, and cyanobacteria to just let them work their way out of the system. When it is something that kills your reefs inhabitants. Then take action. Ya can't sit around on ich, velvet, brook, aiptasia, fluke, intestinal parasites, majano, bryopsis, and dinos for the common issues. Do research. Don't buy everything people say to use. Make sure your tank is level. Have a good export of nutrients. Add live stock monthly. If you can't resist that one buy that was a must for you. Go for it. See what happens. Throw the receipt out after a few months and start a new one haha. Your tank itself will speak in volumes if there is an issue. The smaller the tank. The faster it becomes apparent. Good luck and enjoy the hobby. Best part of it is going to the stores and looking around for your next coral, clean up crew, or fish. Go to frag shows. They are fun for sure and stressful at the same time, because there is so much you want to take home. Just watch out for an aardvark when driving to them.
