My battle with dinoflagellates

[Frogger]

Good luck, it always a process, manual removal outside the tank might be the best option.

it's amazing what can happen in 3 days with just a UV sterilizer when you're fighting amphidinium dinos.
I ended up having to deal with prorocentrum dinos for over a year until I could safely say I won. they were definitely a different beast as they never leave the substrate so UV isn't effective. I found success with algae and introducing some more established live rock.

Hi Llorgon,
Congrats on winning the battle. What a process!
Not sure if you need any free chaeto (with pods, brittle stars, etc) - just let me know.

I have been trying to manually remove some each night by hand. I haven't made much of a dent yet. Some spots are hard since it's attached to the rocks really well and doesn't want to be pulled off.

It is pretty amazing how well UV can work. I think it's the opposite though. Amphidinium are in the sand and don't go into the water column. That's what I had in my sand and the UV had no effect on them.

Thanks! I may take you up on that soon. Although the last stuff you gave me didn't last very long. Maybe second time will work better!

Some people have success with Hydrogen Peroxide treatments for GHA

Hmm. I will have to check that out. Might be worth a try. I do have some hydrogen peroxide laying around.

Ok. You twisted my arm. When you are ready to harvest let me know and I will stop by.

I thought the mexican turbos didn't last long in reef tanks since they came from cooler waters? Or am I thinking of a different snail type?

When I had GHA like that I just scrubbed hard and changed the filter sock 30 minutes later to prevent it decomposing back into the tank. Added a Turbo as well. My tank read very low nitrates and no phosphates so I didn't bother increasing my water changes because clearly at that time it was all in the algae. But if your readings are high then you'll have to perform some water changes or throw in some media to help bring those numbers down.

I would recommend the Zebra Turbo Snail (Philippines) instead. They come from warmer water and do just as good of a job.
