Hey guys I went away for 2.5 weeks and came home to GHA turning my tank into the Amazon. Most corals are shot and water parameters are now good with water changes but read that dosing hydrogen peroxide into tank @ 12% 1ml per 10 gallons will wipe it out and slightly stress corals but not kill them for a day or so????? Thoughts? Don't want to loose the rest of the corals! Ty for thoughts!!!:headwalls:
GHA over run!

Nitrate/Phosphate results?
2.5 weeks will usually not take an algae free tank to the amazon.. Usually conditions were already on the decline,etc... I'm not sure what you define as "good" so you may still have an issue to solve there..
Some recommend peroxide.. some are against it..
I will use it outside of the tank in a 50/50 mix with old tank water and scrubbing with a toothbrush on the rocks.. That works well.. but in the tank can be hit or miss..
A product like fluconazole (sold under the name Reef Flux for this industry) works very well to kill GHA. I'd recommend it vs peroxide..

I put a large Mexican turbo snail in my tank after battling GHA for months. Cleared it in a week. He's still very happy grazing all day to keep it from coming back. I only have a 10 gallon nano, but I tried everything from scrubbing the rocks, black outs, weekly water changes, lawn mower blenny.... Turbo snail crushed it.

What water parameters were bad when you got back home?
I wouldn't dose hydrogen peroxide, personally, but it might work. It might damage fish goals or corals, or both. Fluconazole is a good suggestion, in my opinion, and you might find a snail that will eat it. Snails definitely are hit-and-miss, though.
How unhappy are the corals? If the situation is not an emergency, I'd stick with fluconazole and maybe a bit of hand-pruning. I would avoid spending a lot of time removing the algae. The goal is nutrient export, so getting all of the algae is not at all the idea.

Not enough info here, you didn't answer the Q about what the water chemistry was when you returned, you didn't mention was the tank being baby sat or auto fed, you didn't mention the lighting schedule while you were gone, i could go on & on ...........Instead of focusing only on how to treat this prob how about also focusing on what caused it, treating is a band aid and the reason for it in the first place needs to be dealt with.

Put more crabs in my tank and that got rid of it.
