that question was loaded hA
I did it by using a chemical cheat a few times until the burgeoning mass of GHA was
rid from my tank. Others have lifted up their rocks where new algae was growing, burnt it off with a jet lighter, then that algae that was about to take over turned black and fell off. My only offer here is reject the algae through any means, right when it pops up. If you leave it in your tank to hopefully go away, you might be seeding your tank with regenerative biomass that can make you have to take much more drastic actions later.
Always practice good nutrient control on each tank, and if that doesnt work, we can still act through many means. I personally choose to chemically burn out algae so that I dont have to mess with nutrients. In the end, i have a permanently algae free tank using only basic care methods and thats all I wanted. No tank is free of cyano, they get in routinely and either express as a colony or not depending on variables. the DNA for a potential cyano invasion is certainly in my tank, so I value nutrient management to prevent them.
there are many ways to skin a cat
*little to no reef anarchy is being offered here. Im saying that when the first sprig pops up and you remove it, 0 is there to take over that spot, then the next, right up to a really bad phase for the tank. we have all been taught that disallowance is a waste of time
But we save tanks with it now
Nothing impacts disallowance other than allowance.
Nutrients, bandaids legitimate methods, those control how often you are taking the final step of prevention which is disallowance. An ideal reef prevents its own algae, you do hardly any work. A practical reef needs you to do kill/removal/disallowance often, rarely, daily, it ranges. But its nice to know zero algae can win if you opt for it. For me, chemical cheats are getting me less work so thats only my way. 9 yrs algae free
