I had a pretty big bubble algae breakout earlier this year - every weekend I’d scrape. My tank is a 75 gallon display. Finally got tired of that as the scraping and adding emerald crabs and one spot Foxface didn’t really help - it’d be back the following week. Just too many areas you can’t see and get to when you scrape.
I saw a thread on Reef2Reef from
@brandon429 about using peroxide. His suggestion of pulling the rocks and spraying with peroxide did the trick for me. There’s still some in the system, but it’s only a few that I scrape and siphon into filter a sock before I do a water change.
I didn’t do all of my rock at once. Did it in 3 or 4 groups every few days.
When I pulled the rock I took off all of my frags - fortunately I didn’t have a ton of coral.
When I took the rock out I sprayed it with 3% peroxide that I picked up at the store. Let it sit for about 5 min and then scraped and scrubbed then rinsed with fresh saltwater before putting them back in and re-glued frags.
I’ve had it under control since then. I think the crabs and Foxface can help keep it under control when there isn’t a lot and the bubbles are rather small.
It’s a drastic step, you have to redo your aquascape, but it worked for me.
Also, I know this forum is about 50-50 on whether to pop or not. I say scrape and pop away (as long as you suck out what you can). The crabs and Foxface pop it when they eat. That’s my story and I’m sticking to it.
Good Luck!
