The most important trick nobody relays about gha is in the first sprig we see
100% of the hobby says leave it, new tank uglies and then +6 mos later in full takeover a different set of advisors are at work in the tank emergency forum right before shut down. Or perhaps hands off more morphed into full cyano takeover, name the opportunist it's all the same cause.
But the first sprig= crossroads. You can kill it or farm it, those who kill it never wind up in the emergency or nuisance algae forum
You get to quit manually killing when you arrange variables to luckily halt it for you, before then it's manual kill.
It's not that gha is bad or means bad water. It means we don't want certain DNA expressing in our tank bc of a look we like. Since we are preventing something as suited to the reef as coral, consider gha not an enemy but something you should cull for obvious reasons. Vs dosing your water and reacting endless months, this is perfection against gha, it can't win:
Arrange your rocks not in an inaccessible stack, but in a manner you anticipate needing to take them down for external control. When you see gha, or anything you don't want to risk, simply lift the rock out and set on counter, dentistry time literally.
Metal tool, knife tip, dig the algae out at the base like a man grazer leaving a tiny invisible dig, algae gone like rasper X on the real reef
Put two drops of peroxide in the former anchor spot, wait one min. Set rock back in tank and work on your lucky arrangement to never have to remove rocks.
100% of gha tanks are caused by watching it grow, sprig by sprig, frozen in inaction. Everything above is the polar opposite behavior of that which causes all gha invasions. It's a behavior, choice, not a plant or chemistry issue. Weird huh
