Hi Luke thank you for stopping in
I hope you will see a recurring theme in the thread is algae kill even when not necessarily by peroxide. The posts here outline the possibility of whole tank dosing, especially the underwater spot injection techniques from the last six pages check those posts out in detail.
The cellophane capture might be especially suited for gravel use
Need more close up pics can't see the kind of algae but then again we said ID doesn't matter
and it doesn't, we kill all kinds except neomeris and some deep seeded valonia lol sorry snakebyt pal from lubbock
But if your tank was mine I wouldn't start with peroxide
For all substrate invasions I start with dedicated removal of the patches of substrate via siphon or scoop
Small portions, this is nutrient releasing as it kicks up small clouds of waste. Change water well during your peroxide work, its a time of change for your tank you aren't keeping things the same and the captive reef will adapt. Be creative with peroxide work, ponder how you can get it in and out quickly, or any little side maintenance things you can do like detritus removal if you will already be deep into the tank anyway
Have a partner hold your siphon hose so when you scoop up a substrate sample for cleaning they are there to remove that waste cloud before it casts around. In tank use should almost always be a pumps off application technique. There should always be the initial test sample portion in any in tank work...we aren't jumping off and doing anyone's whole tank first pass.
Maybe do a small portion as peroxide underwater spot injection, then the bulk as manual removal of substrate portions with clean and replace, see which patch looks better after a week before evaluating the whole tank as a peroxide method fix
I'm always thinking manually remove more than you dose in tank, those who test that mode on a small section vs running whole tank right off the bat nearly always revert back to external treatments at least as the initial kill.
You correctly id'd the sensitive animals in your tank so thats either a quarantine date or let's go cold turkey on this bad boy and see if they survive. For any in tank work I predict the sensitive species will not.
Also consider this variable
I don't recall anyone in fifty pages dosing vodka or any other carbon source in conjunction with peroxide
Its uncharted
*thank you* for mentioning that my concern is a future date in tank doser will forget to mention that practice or exceptional chemistry situations where people target high end alk parameters. Perhaps its harmless like a lot of the aspects of peroxide use, don't know.
What does the peroxide do to your bacterial complexes which are the key association with vsv methods? Anyone answering that pro or con is a guessing man or lady, its not been formally studied in marine aquaria. none of this has, we get first documentation among many web threads where others post their findings with in tank peroxide work
Your tank can be as experimental as you like, but if we brainstorm and type first, before work, your tank comes out safe like the rest
I recommend all in tank dosers consider the effects to their tank of stopping vsv work, heavy photoperiods/intensity for high level in tank dosing (recall some of our calculated upper limit doses were in excess of 4 mls per ten gallons) lowering high alkalinity maintenance which is a known stressor to sps, and we start brainstorming anything that interacts with oxygen content or free radical production as separate from in tank peroxide work and not to be ran at the same time
If ceasing a current method of major tank chemistry support would stress your tank, I can't see how adding peroxide to the mix will help things. Consider this before starting.
My tank doesn't use any alcohol help we just down a bunch of 35% up in here let no keeper judge another's crutch lol
Using more gfo and phosphate stripping is not recommended as a recurring theme in this thread. We are removers, those are preventers. Some have success with any method of algae control, algal turf guys can starve it off your rocks. Nutrient restrictors can starve it. Grazer specialist will have it picked clean regardless of the po4 levels in your tank, the key is what is right for your tank.
Rather than convince anyone to try this, I recommend you do all others first.
