Hi J

 

thank you for posting that is a great documentation on your other thread, I scoped it out.

 

Your progress looks like 95% of the ones we've captured for the various peroxide threads. being 3 years into it and neck deep in wrecked tanks online :) I was about to forego 3% as a recommendation and party at the 35% level, my patience has worn thin for tank invaders after 36 mos of various dosings lol

 

but your excellent pics remind us why nearly all peroxide threads are using 3%, that ghost white algae after effect. on tanks not getting zapped 24x7, the 3% works nearly all the time. grow back is your variable, especially with bryopsis. the holdfasts run deep! thats why it hasn't let go yet. it will though. after becoming impatient I started using 35% in my own tank, carefully of course, because its just so dang mean to algae. it cuts it like a powersaw, and your skin too if any gets on lol. prob best to save that fuel for the bad stuff, 3% worked well for you.

 

but those same deep holdfasts in the bryopsis or whatever strain this is are the progeny of the regrowth as well, so there are ways of dealing with that. The only thing I would have changed on your thread was any time a presence of ammonia is detected in a reef tank, it should be made to zero as fast as possible. .25 and .5 are unacceptable values where living animals are present.

 

But, you were using api. and you didn't mention labored breathing by the clown which will happen at a real .5 reading, Im not sure what your actual ammonia levels were but in general practice, if you ever detect any, make it zero.

 

the few days lasting effect on your frogspawn and your zo's are common for in tank peroxide dosing. irritating, but not lethal etc. same can be caused by a standard large water change, these nearly always come back just fine and by your after pics looks to have done that. Might be nice to keep some Prime conditioner on hand to handle any ammonia should it pop up again.

 

its very possible some ammonia was liberated into solution not by bacterial loss from peroxide, wont happen at 3% levels, but by disturbing large organic stores when relocating the rock.

 

susceptible worms like bristleworms decaying could also make a brief spike.

 

Per your after pics the tank is simply readjusting, and if you have grow back you will have to act fast on it. those rocks were really invaded before treatment, its ok if peroxide is more a control mechanism and not a total cure. mg boosting might help, clean up crews might help, you might have to lift out the occasional rock and spot treat again to get the new whiskers, thats the imperfect aspect of peroxide treatment for bryopsis, getting a one off cure is only for the lucky. typically you have to redo it as needed until we figure out something better or someone gets pretty lucky.

 

Previously, bryopsis just wrecked tanks and we started them over. now and per your pics, it doesnt have to be that way. peroxide is a perfect mid ground until advancements give us something new. thanks for your great documentation Im linking this thread to a recent post of mine in our big peroxide thread here.

No actually the counter, I choose to always expend the effort to remove and externally treat with undiluted peroxide

 

simply because we are lucky if bryopsis stays gone and to further dilute the peroxide lessens the chance of a thorough kill, plus it exposes non targets to peroxide

 

there are many cases of whole tank dosing you can see, I just prefer the other I think it kills better

 

just my opinion
