Need details on Shock & Awe pls.
Reef Agent Orange:
OK. First let me preface by saying use at your own risk! I have used this in my tank on a area about 6"x6" with no ill effect. I would do small areas over several days vice doing the whole tank at once. If it is possible to remove the rock to a bucket of tank water with a heater for application that would be preferable.
My test on this tank did not show any appreciable change in water chemistry with the exception of a small rise in nitrates. Mine is usually 0 and I got the hint of a reading 2 days after the dosing, presumably from dying algae matter. This was handled with a WC.
The principle is that you are creating a localized negative osmotic reaction that disrupts the cell structure of the algae. The recipe is very close to commercial solutions for killing aipstasia. This is just cheaper (by far), particularly for the quantities needed and the ingredients are things most of us have lying around.
Here is the recipe:
1 oz boiling distilled or RO water
2 tsp kalk powder
1 oz sea salt mix
Mix well until fully blended to a paste-like consistency. Reduce flow in the tank as much as possible. If feasible, shut it off for at least 1 hour. Remove as much macro manually as possible to reduce how much paste you have to use. Use a turkey baster to apply the paste on top of the macro (mine is a sp.of caulerpa). Be generous in the application. WARNING: this will kill corals as well!!!! Coralline may show bleaching! Microfauna in the treated area will vacate quickly. I am sure there is collateral fatalities to pods, bristles and micro stars etc!!! Again, use at your own risk when the potential benefit outweighs the potential adverse side affects.
In my test within three hours I noticed the algae turning pale. This continued even after full flow was established for the next 2 days. By day three the caulerpa in the applied area was totally gone, to include the rhizome.
I have not yet tested on hair algae, although I have a bit in my tank and plan to while eradicating the rest of this caulerpa. I do not know if it will work with bryopsis. I do not know if it will make some species of Caulerpa go sexual, although I think this may be a risk as a reaction to stress.
My test was performed on 2/3/10 and to date no macro has reinfested the applied area. That being said I have only performed one test so I do not know the long term effectiveness.
I will post pics on this thread over the next week as I treat my tank. LMK if you have any questions.
