Practicing the rule of exclusion as primary algae control in my own tank, analysis:
-invader is obligate hitchhiker bubble algae variant, reddish bubble algae
-got in by simple import. I selected a clean looking frag from lfs, turned out not to be clean apparently heh, the pic shows bubbles forming at the edge pushing up tissue. About three bubbles so far, means more are coming. The rule of obligate hitchhiker battles is once the target DNA/all possible mass is excluded, including by direct action chemically if possible, it cannot come back until reimported.
×non quarantine is the sole cause of why there's an invader in my tank, not nitrates or phosphates. ×
-related to other threads, this invader ranks high in invasive adaptivity, so I'll act now, not later, and decline it's presence.
- I've been blast feeding my tank ridiculous for one week to fatten up some distress frags I bought, I'm sure the botry likes the extra nutrients coincidentally but this isn't a nutrient-modulated invader. It requires hesitation after initial visual inspection to take over a tank, and, a rockscape that is inaccessible which causes the keeper to be hesitant. I'll select oppositely.
-plan of action is certain. Lift out this frag rock set it on a plate. One drop of peroxide on all three bubbles, which will contact polyp tissue as well. Lps are known tolerants of light directed contact. That corner will stress a little, maybe lighten a bit after my dental profi angle picking coming up, but it will heal faster when these bubbles are gone. I will have to scrape a little up under the tissue, some minor insult is coming. It will heal and be fine if I get this stuff out now.
After sitting three mins straight contact I'll pick off the bubbles and hit the area again with a drp of 35% then place it in the tank, low tissue contact time.
Prognosis: will not have an invasion.
I took about fifteen minutes in the air. Found two more other side of polyp and zapped then clipped on a plate. I squirted saltwater on the corals as rinse and hydration but the target areas were in air and hit over and over with drops then rinse.
Put back in tank will be able to assess next week. No other areas had growth I think I caught in time. Any part of my reef is accessible in case I didn't. Bubble algae will not win. <----how many counter options are implied in that statement=this tank is immune to takeover, and I don't even own a nitrate or phosphate test kit and never will. once this is killed, ill never have to treat the bowl until next import, and im through adding frags now.
This green brain got blasted with peroxide multiple times, they are tolerants as are most known lps.
24 hrs later no harm and there was much direct contact:
No algae yet.
And this on Monday night. Feeders out fighting with brother acans on rock no algae thankfully. Full attack did sway outcome

Above is a peroxide turnaround from friends at nano-reef.com and he has sensitive blood shrimp in his tank + anems
. I need to find out where I can get the 35% peroxide from. I've also noticed that some of this stuff is now growing out in-between the newly encrusted parts of my sps arrh. So I'll have to hit those parts up but will have to do the 10% or so of peroxide.
