Brandon, I know that people are leery of dosing peroxide directly in their tanks and are afraid it is going to create all kinds of issues and problems. Let me add a twist to what you have been advocating: I have dosed 5 ml of 3% H2O2 directly into my tank to see what effect it would have other than raising the O2 level and reducing the DOC.
Nothing untoward happened at all. Zoas closed for maybe 20 minutes and then re-opened just as nicely as before. GSP retracted for about the same time. No other corals showed ANY sign of even being affected and that includes a 3 head Duncan, a 3 head Candy Cane, a 2 Head Leather, a 1 head Leather, a tiny red mushroom, a Ricordea florida, 2 fairly large Ricordeo yumas and more.
No reaction whatsoever ... all I noticed is that the DOC was reduced (the how fast do bubbles at the top of the water pop test was used as I do not have a way of testing DOC by any other method but when bubbles pop faster the surface tension is obviously lower due to less DOC and so they pop just about immediately after they form).
So, to agree with you, yes treating outside of the aquarium works for sure, but when used directly IN the aquarium I have not seen any negative effects either.
Now one has to be careful obviously about how much is added and not dump large quantities in the water all at the same time.
Start with a low quantity and increase it as you go along, and when you Zoas react you probably know that you have just about reached as much as you can add at one time.
The next thing to do is to add the quantity every few hours rather than maybe once a day.
I have used the method to raise the water quality dosing 5 ml in a 20 gallon tank (minus what the rocks displace) every 3 hours, for 4 times in a row, so 4 treatments in one day, and have not seen any adverse effects at all.
FWIW
