I chat about it there but it’s hard to get consistent before / during / after of the technique as there’s always a bit of theory discussion as well but that has the general approach.
Rasping is imperfect in that it’s a hands on, roughshod way of handling reef materials (in a world ruled by water actions and nutrient actions/hands off and detritus storage)
But it has an edge over other procedures being purely target centric and never touches coral...never subjects the whole tank to changes that corals may dislike. They’re easily kept wet / squirted w saltwater as we work externally
If someone doesn’t mind the direct access part, then rasping and a test rock determines how deep to rasp, how deep is based on the penetrance/growback of the anchors for the algae at hand
The few limited times I had to do it in years past on my rocks I only had to use a kitchen knife tip to precisely dig out the offenders, rinse em off, then peroxide the cleaned areas for cellular cleanup
I had to do it a couple times in guiding but this helped me see my own invader wasn’t that strong or deeply rooted. I got a little lucky and it didn’t come back
Sometimes there are 10-20% raspers where it does grow back too fast to be scalable for the big job, at least we’ll know off a small test rock before doing the big job, it’s at least nice to have a window to view the small scale work
You sure are resolved to keep fighting the gha. Nice / rare keep trucking there are many who want to see if you can dent it
Also I have one other ace in sleeve
I never use 3% that’s just what we work with in public for safety so that people aren’t harming / blinding themselves accidentally bc regular peroxide is safe to work with (and the trade off is being weaker on target, I’ve no time to play w invaders it’s war)
I use 35% which is liquid cobra buzzsaw, what it does to a target is nothing like 3% and the user must wear glasses eyewear protection, no room for mistakes on 35% but that’s what I used post rasp, it’s killer mean stuff, your local health food store in the refrigerated section twenty bucks a quart
The level of work you are willing to consider is rare, most are on the give up phase as of now. The veracity of your target to external work, nutrient controls and no sandbed fueling things just screams for the cobra
we really need 35% here it’s indicated imo, if you get it on your skin it’ll burn it a little but nbd, I get it on my hands commonly as I still use 35 on a paper towel to wipe inside of glass when tank is drained
But there is no room for eyewear lazy one drop on the eye, blanched cornea no heal, the stuff shouldn’t be sold OTC but it is, and it’s the best algae implement I’ve ever seen for external work...3% is a group of little girls wearing soft cotton gloves selling cookies comparatively heh and 35% is a bag of liquefied hungry + rabid pit vipers which take to algae like a wounded rabbit
