My battle with dinoflagellates

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.

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.

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.

Not sure if you need any free chaeto (with pods, brittle stars, etc) - just let me know.

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

I have a great big ball I have to harvest soon.

Great to hear you hung in there and won !
Big Mexican turbos eat the green !

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?

I’ve had the same 3 turbos since starting the hobby haha

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.

Not sure I would want to dose H2O2 directly to my tank. I have tried it before to control algae and it did not work unless you use it in an Oxydator.

You do not have a lot of rocks in your tank. I would just take them out and scrub them. Add some CUC to keep it in check. You might have to do it a few times.

If you really must use peroxide I would spot treat out of the tank. Only problem is peroxide does a great job on the hair algae but it also toasts coraline algae and amphipods/copepods as well.

Be careful how quickly you bring you nutrient levels back down or you could cause a cyano outbreak or worse back to the dinoflagellates. You haven't eliminated them only created a more balanced system that out competes them.

Chemical cures can also create an unbalanced system which leads to further problems.

The Mexican turbos that Aquarium illusion in my area get in are very large as turbos go they live along time but there like bulls in a china store.
Another very good snail are the strawberry snails but over time they get big and again if corals are not encrusted or on plugs they can move them. The strawberry will grow bigger than the Mexican turbos . Both are excellent grazers.

That's impressive. Snails seem to be one of those things I really struggle to keep alive. My survival rate seems to be 1 in 5. I have no clue why.

What do you use to scrub the rocks, just a toothbrush? My nitrate and phosphates are high. So no mystery as to why I have so muh algae. I'm working on slowly lowering them. Where can you get the zebra turbos?

I agree on the H2O2. After reading more into it it seems like it usually will kill more than just the algae. Which I am not sure my tank can handle that at the moment

For scrubbing the rocks I just scrub them in some saltwater and then put them back in?

I'm worried about lowering the nutrient levels. You are correct the dinos aren't gone just out competed. I can still see some on the ends of the gha. I'm trying to lower them slowly with small water changes each week. Also trying not to use as chemicals either.

I really want to find a good balance between appropriate nutrient levels to keep dinos away and enough CUC to keep algae to a visible minimum. My main problem is finding the right combination of CUC and keeping them alive.

Interesting. I will look into the strawberry snails. I haven't heard of them before.

What about emerald crabs for gha. I have heard they are good for eating it, but can get aggressive to fish or start eating some corals. Anyone had any experience with them?
