I cannot tell you why this stuff comes abou
The number of tanks like yours Eric aaa featured in the linked threads above might be 10 or 20 from the rc example alone
In saying your tank can be fixed, that's coming from the after pics we collect.
Sea hares, urchins, tangs, all good natural options.
Actually fixing your tank includes more work beyond algae, to be done right. Your brief pics indicate eutrophication details such that detritus will be elevated and retained in this tank, have to remove it. The growths themselves hold much, and plug up the rock with detritus and reduce flow.
Thankfully it's easy to fix, no need for new rocks just some work. Same as the other outcomes linked. When made free of retaining growths the live rock will purge detritus a while and all that means is have the rest of the tank already free of waste so it won't compound and can be removed for a true fresh start.
t, but according to my experiences and what people have to say is it will never go away unless swap your rock, yes you could keep it in check but your going to have to keep a billion hermits, snails ect w.e eats it or just change your rock
Thank you so much you are one of the only people that recognized it as something more than just your run of the mill gha despite the crap quality of my phone camera i am running chemi pure blue wich contains a phosphate remover but it's not gfo I don't want to run gfo because I have been dosing red sea no3 po4-x and am going to continue using it until I run out then I'll probably just dose vinegar. I did get new rocks and it already got a small patch of the crap on it I will have more pictures tomorrow tank looks 10 x better now that I have it somewhat under control I'll just try to keep it that way. I did order 3 types of calp so that should help. I don't have a fuge but have had great success with calpuera in the tank before until gha took it over I removed everything from the tank except for my fish and coral. But thank you very much everyone keep the tips coming I really do appreciate it. I just joined today and already I am incredibly impressed with the hospitality of this place! ☺Its not bryopsis the bottom picture is chrysophytes, was acually just talking about this in a thread sometime last week

. You did say it isn't GHA I'm just saying use similar methods is all .... I take care of a 380gallon system up the road that had a wirey green algae and the emerald crabs loved it ..... It's gone in that system. Took a lot of work though. Its fun sharing info
