Bill, the reason why is the same as why do people dose carbon or vodka when they could just keep a lesser bioload, everything we do is a bandaid for nondilution. If you started a thread beconing just cyano entrants only, where people give live time feedback, many tanks won't comply as shut -and-close as it may seem.
All cure claims must be backed by cure threads I think. Zero formal articles, those are safe zone works heh.
i agree about control of waste sinks, that's why I'm cyano free I don't need peroxide for it. But in addressing needs of the masses, not everyone agrees to a recommended trial cleaning run and many post growbacks after following advice which is the unique accountability threads provide. Invite just 20 algae problem tanks into a thread, try and fix off those basics alone. Herding cats heh
More is required to run such threads, beyond the basics. Some do it with algae scrubber arrangements, we are all offsetting dilution issues.
On the peroxide thread linked earlier which we focus for about 200 combined pages on algae, and not cyano, your thread Todd has valuable additions for us to glean about its expanding range of biological applications. The primary value of 200 pages of all types of algae/peroxide in tanks is seeing repeating variables. Some of the tanks were sps tanks worth twenty grand, in the reefcentral peroxide thread specifically. Those pages buried among type anecdote actually house pics of every known reef tank inhabitant pre and post dose, but that stuff comes in messy bulk and among much to sift. Price of free data for the taking=bulk posts.
Very large threads exist comparing the non catalyzed addition of peroxide as is considered here vs the catalyzed and isolated breakdown within an oxydator. The impact difference is the list of known sensitives with the non catalyzed version.
Cyano is an ongoing threat even in freshwater tanks. I have three annoying patches of green cyano in a work terrarium, it's everywhere by design and your thread is valuable work angle to see. There is an unending, absolutely unending demand for in tank dosing. We dose vodka into the water. Stump dissolver. Mag flake from Home Depot. our hobby demands to know more about full tank dosing and dilution mechanics for the tools we use. This thread you have made with momentum is gold.
This will become a collection of whole tank dosings which we value tremendously. key take away from 200 pages worth online to save someone from a years worth of sifting:
At no degree in any dosage in any overdose practically speaking are filtration bacteria or denitrifying bacteria affected. Good luck producing reef tank results to the demonstrable opposite, our number one claim is that due to variables not considered all bac in concern are housed away safely even if you dose the whole tank. Even with 35%, I have videos of putting 35% inside a tiny one gallon reef at the tune of about five mils. Peroxide dosing no matter how long you sustain it within reason (I didn't say 100% peroxide water, within reason as people do) isn't harming, changing or affecting any form of ammonia oxidation measurable with accessible hobby kits, the ones we base entire tank actions on when not considering peroxide
Most every coral and clam known will tolerate the dosage of one mil to ten gallons, that's our working safe zone set to the tune of what zapped the most invaders in the early testing runs comprising the old threads after JC posted his findings and pretty much introduced peroxide
Peroxide as full tank dosings, the 1:10 ratio, the forums did that. Forums always wind up dumping things in the water, recurring theme about supply and demand. They were shown external treatments, someone went and dumped in a liter the rest is history
The most sensitive animals we keep to peroxide in order in my opinion are lysmata and cousins #1, some always get lucky, hermodice fire worms (tanks with known many might preclude peroxide dosing) xenia, decorative macro for clear reasons (we fix macro invasion tanks with it x a hundred) many anemones get mad at it but don't die, coralline bleaches and then you have odds and ends, statistical outlier losses from unnamed variables such as "I had zoanthids die" but they were withdrawn and isolated and not communal...tall/lanky on the way outs. We watched for patterns to get our list of sensitives and tolerants. In the higher doses exceeding 2-3:10 those pre-stressed corals may start to give more but by and large our threads shown just about every coral kept as tolerant, within reason.
Using full mode lighting is amplifying grossly the action of tank wide peroxide. If anything is on the brink, people need to cut back lighting as if it was a new light and ramp up after your main targets are assessed. Watch out for these hidden and profound peroxide amplifiers (likely involved in the outliers)
Alk spikes will kill when combined with peroxide
High lighting especially whites
I do not know what effect uv has, probably degradative not sure
Lower your alk a safe bit before full tank runs, if you run high alk typically. Def don't do extended bright lighting, high alk and peroxide unless you have the worst invasions that's a coral bleaching formula, but ironically a line to consider walking for the meanest ostreopsis Dino invasions responding to nothing.
Zoanthids are the most tolerant of all corals
I routinely blast all mine with straight 35%, blanch $60 zo colonies white and closed tightly, only to have them open in one hour. As testing. Mine are colonial, compact, well fed and I don't have outlier outcomes
resoundingly across posters in our collection, zoanthids are top strengths I bet it's that pachyderm-like cortical layer when they are healthy.
Everyone should find the gross overdose threads for fine learning too. Russ, a poster here, has the finest continual guided overdose on an sps tank I recall. Many sps subjected to far worse than person X did when they added just a bit too much, and are now concerned about cycling or coral loss (see first tenet, no requisite bacteria are harmed=a claim inviting testing in reef tank conditions, prove the null anyone and post back)
Regarding the safety of various people trying tank wide dosings, it's my opinion it's not that big a deal to consider the sensitive organisms, run a squirt or three and post back. I know T wasn't trying to advocate anarchy just thought I'd toss a hat in reflecting on a gazillion hair algae dosers who did the same thing.
**the best efforts are reverse of the normal inclination, to dump peroxide into an invaded tank to see if itll clean and reduce for you. We should hand clean out all visible cyano via export and water change, work hard as your cyano indicates waste reserves as causative in 9/10 cases, then try your peroxide tests on a clean tank, solely as growback preventive. That specific tweak will take a hundred non compliant tanks and make them comply. The work element was missing, detritus has set in some ***** sandbeds I'll guarantee, and if you undo your nonwork first, dose second, you amplify the effects of any dose against your target in the most basic and non bandaid way.
very detailed example threads exist to show one how to clean out a cruddy sandbed and not recycle a reef tank, a few are on my profile page.
Had a lot to type Team, night
) If the peroxide is only staying active in the system for 24 hours and you have to re-dose every 24 hours, how is it targeting cyano or nuisance algae? I was recently dosing 1:10 to target said bryopsis; however, I decided to pull the large rocks for a direct application and scrub with a toothbrush. Is the continual dosing administered in hopes that it eventually finds and attacks its target? Or is the continual dosing attacking the target slowly every day and eventually eradicates it? I hope that makes sense! I'm just trying to know how it is working within the reef.
