check that out, we use it in gallon sps reefs. single gallon sps reefs
you're right about hands and eyes. The reefcentral peroxide thread running 6 yrs has tons of use in it, google pest algae challenge thread. we guided 35% use in tank across fifty tanks there. its power juice, like when you drag race not using 88 octane lol
if this op automatically cant remove rocks, cant drain tank, can't rasp, then amp up the juice on a single 1 ml test spot using one of the underwater applications. you can use a few mls on target underwater injected slowly into a large tank, id do it drained however and not in the water. id remove that rock and force win that battle, or use some of the new dosers out to see if they work. we have decent documentation though for the p
I agree its highly ironic that something that can blind a person is a great awesome reef algaecide. I used some in my tank just last week, a gallon vase decade old. I let the insides get all scummy and then when drained, I wet paper towel it inside w the 35%, rinse and fill up.
if his tank was mine id lift out a test rock, rasp, hit 35%, and assess that in a week. if its awesome outcome, then do drain treatments only one spot at a time, not removing the rock is going to make more work in the end. It all comes down to hesitation, this was easily prevented upon first detection, its a requisite hitchhiker invader that happens from non quarantine and from the letting the original mass anchor in. If vibrant works as is claimed in the big forum up top, then peroxide use will begin to phase out over time due to its careful dosing/application techniques required.
we like it currently because of its online track record and the predictability of what it will do to this algae...but its sensitive animal list is considerable and that doser Vibrant claims to have no side effects, just fixes every known invader. nothing wrong w trying that too, it wont blind someone lol.
here was the peroxide part of that link
