With all due respect, and I hope you take this the right way as I mean no disrespect to you at all.
To you, this is a weed. It's not a weed to me. It's a proto paly whch may not be as attractive or appealing to you or many others because it doesn't have cute name, or it isn't fetching a high price tag, or it isn't as colorful as your other polyps. If this were a stunning blue zoa or paly, you wouldn't call it a weed nor would you be so quick to get rid of it. Instead of dreading trying to get rid of it, do you realize the wealth of knowldege you have to share?
I have waited and waited, but you haven't shared what it is that you are doing to achieve such great growth. Sir, you must be doing something right. I see you have a serious profileration of purple/pink coralline algae gowth all over your tank. Do you know some people can't get it to grow as it is greatly desired by most serious reefers. Again, you must certainly be doing something right, so why haven't you shared what it is?
I see all of your other polps in your tank and doing well and growing like gang-busters for you. You must certainly be doing something right, but again, you haven't shared that.
I see LPS, SPS and soft corals cohabitating and all doing very well in you tank. But you haven't shared with us anything about what you are doing achieve the right balance in your system to achieve this. My friend, you are sitting on a wealth of helpful knowledge to a lot of reefers both you and old, and your focus is killing or getting rid of something that is only doing what it is suppose to do...grow. So share with us all th good you have to offer.
So share with us all of your parameters including Salinity?
Type of make up water and salt?
Water change schedule?
Lighting kind, type, k value, ballast etc?
How old is your syetm?
Do you feed, if so, what and how often?
Reefing is not about killing, it's about growing, learning, sharing and achievements. If you have to remove your rocks and cut away all of these polyps, then I would highly recomend it. But share with us the good news you have to share and your success in getting them to grow along with all the beutiful coralline algae an a welath of happy and healthy livestock my friend.
Thanks for listening as I mean well, I really do and no hard felings at all.
Mucho Reef
