Going dark to cure algae

Hydrogen peroxide has worked for me. I did however pull the rock for about 15 mins. Pulled it and let it sit for 5min then spray and let it sit like 10. Rinsed it in my dirty tank water after a change.

I took the rocks out and dosed in a bucket with a mix of hydrogen peroxide and RO/DI water. I killed the algae temporarily but lost a yellow toadstool and a blue tuxedo urchin died. Did you lose any fish/corals?
 
I didnt loose a thing. Nothing but turf algae on the rocks I pulled. I rinsed heavily after. It killed the algae but good husbandry keeps it away.

Interesting. You said you pulled the rock from the display tank and let it sit for 15 minutes. Five of those minutes it just sat out in the open air. And then you sprayed it. Do you spray it with pure hydorgen peroxide? Or was it a mix ofwater and Hydrogen Peroxide? Was there any corals on the rock? I'm wondering if that would be dangerous to the corals on the rock to have them out of the water that long.

Thanks!
 
hello! I have a nano tank rn 13g and like you I battled algae forever, finally I figured out how to beat it so let me reccomend what I did.

1. Up your flow
2. I would increase your 4g WC to at least 10g once the algae is gone you can work back down to 4.( in my 13g I do 5g ever 8-10 days)
3. Decrease lighting photo period (possibly intensity too)
4. Add seachem matrix/ marine pure in a high flow area
5. Vacuum your sand in very small areas to begin with
6. Snails snails snails a few hermits more snails, turbo snails, and a emerald crab or 2 ( I had a really good one that just passed ��, he eliminated my bubble, and the crew cut algae)
5. With the Phosguard the most important thing to remember is that you must change it out!!! I too didn’t change mine all that often but once I was determined to beat the algae I changed it every 4days then gradually every WC and now every 2 weeks.

Good luck!
 
Another factor that made a difference for me where I used to live was how much natural light was hitting the tank. Does it get lots of sun? If you are ramping up at 1:00pm, there are a good 5-6 hours of sunlight before that time that might be adding to the algae's ability to grow.
