I assure you peroxide is the only thing that saved my reefbowl.
been doing reefbowls since 2001 and of course all original reef training says not to touch the reef pretty much, only actions we can take via the water/parameter controls were allowed to battle algae and various invasions. my first reefbowl 2001-2003 died of hideous red and green algae that I could not get out of the bowl no matter what I tried, red slime remover, chemi clean et al (the indirect means of the old guard)
so on round two reefbowl, 2006-present, I simply had the mentality that I'd take out a rock and blowtorch the section of algae if required as opposed to letting it take over and I passively sit by.
I knew sandbed waste built up 3 years in a one gallon vase was feeding a LOT of my invasions...so I told myself I'm going to break from no-touch tradition, and take apart my vase and rinse out the sand even if the sages said not to. if the reef died from that, so be it, at least it died while being manhandled clean vs passively watching my investment die a second time.
I did use blow torching lol, there's youtube videos on it. works but isn't very efficient
wet live rock is such a heat preventer that the holdfast cells of the targets aren't really burned, even if the topical growths are burned.
it was a lot like lawnmowing where the growback is fast.
Then I saw this thread in about '11, combined with snippets of what JCredabel put on some early blogs and I figured why not try peroxide and then the whole game changed.
it did NOT kill my reef
it did NOT cause a recycle
it did kill my algae, though cyclically I have to apply it occasionally since our reefs are always sinking back up the waste we remove during cleanings and because algae is rarely totally eradicated from a reef only suppressed
I honestly believe my reefbowl has had the most 35% peroxide put through it of any reef alive, and it's certainly had more rip cleans than any reef alive, which is why its the oldest pico reef alive. peroxide the world's best cheat saved my reefbowl and it would not be alive without peroxide.
I no longer care if it's cheating to force a reef to run seventeen years looking 100% not ever invaded, I'm just happy to have old corals for once.
peroxide is the most important tool I've ever seen in reefing.
year seventeen, due to peroxide:
not one single invasion at all, the entire time, because it wasn't permitted. I didn't luck into that, it was forced not coaxed. I never dosed peroxide into the water though, I take out things and put peroxide right on the target.
one day it will be nice to not need peroxide, but that day has not come. there is no replacement for it's utility currently
this thread should never be unstickied its among the most tank-saving threads on reef2reef.
