I believe we can cure any tank of that algae. A benthic invader on rocks that can be lifted out for special access is lucky among possible invasions. I'd take that above over any risk of valonia for example. A test rock is worked before the whole tank is attacked

From a single test rock, one of a couple tested modes is extrapolated up to the rest of the rock and they follow because the test rock followed.

That article above shows water params aren't the control for algae on fine reefs, lack of rasping is the cause. They boxed off sections of a normal reef and grew algae just by keeping rock biters excluded. We can cheat those results by manually debriding the rock surface of that anchored invader, then use strong not weak peroxide on the cleaned area, not the pre cleaned area like everyone else does. If doing a bunch of work doesn't sound fun, at least do a test rock to see how well it works. One of a few current dosers people are posting about might work, but I'd take care of that with a steak knife and some 35% peroxide that sits in my fridge with a big skull and crossbones drawn across the bottle.


That algae you have was a requisite hitchhiker which runs independently of nutrients, it needed only import into a reef and nothing beaking it off the rock, which is quite easy to replicate with a kitchen knife and some 35%. I would have that rock cured in two weeks. All external work, sitting on a towel on the counter for precise spot delivery/surgery, leaving the fine coralline surfaces untouched as possible. It's detail surgery in the air, but I'd work within 20 min timeframes each round because you can skip cycle live back into the tank within that timeframe.

That article wasn't meant to imply I think a grazer animal is the method to fix your issue. It was to show nutrient independence for anchored invaders and mechanical cheats we can employ right now which mimic nature and makes a reef tank comply instantly. It's work/command results now vs dose something and wait. The urchins and parrotfish score the rock, chew it up like algaechalk, then poop out sand sans algae. The steak knife wedges it out, the peroxide digests the bits not rinsed off. There is a medical approach to curing your issue, it's the only one I'll use I don't care if it's a cheat.
