Dinoflagellate Problem? Could Ulva lactuca be the Answer?

Bump.

Did we ever conclude Ulva helps beat Dinos? I am dealing with Amph. Dinos currently.

So far dirty method is helping but very slowly.

For Amphidiniums i would dose waterglass/sodium silicate induce a diatom bloom too outcompete them

I think this thread might be worth a bump. I know it's a couple years old and 100+ posts, but re-reading it, there were very few who tried it with microscope confirmed dinos and successfully growing fresh ulva - which was the most effective according to research.
@Cory what were your thoughts / observations on this? I know your dinos came back more recently than your posts here.

@Dan_P was seeing a weird clearing around his ulva growth that reminded me of this thread.

(also maybe this thread should hang out in the nuisance algae forum?)

Potential demonstration of Ulva allelopathy. Plastic mesh on left covered with growth, right side clean as a whistle. A Garcilaria species on the left, Ulva on the right. I have not characterized the growth on the mesh. Will update when I do. By the way, possible allelopathy up close to the Garcilaria clump.

Well they came back and i didn't have any ulva on the system. Now that i have a uv sterilizer on the system the dinos are gone. However when i had ulva and increased nutrients i noticed dinos dissapeared quickly. But when i tried again without ulva and raising nutrients, they didnt decrease at all. I find the tipping point for dinos going away is when hair algae comes back.

The fuzzy stuff on the screen is what I’ll call a slime ecosystem. This is diverse ecology. There are samples one might be tempted to classify as a diatom mat, in another a bacterial mat and yet another a waste mat, all sorts of discarded exoskeletons and nematodes. Whatever the basis is for this mess, it does not seem to take hold near the compartment Ulva. It is a very interesting observation but not sure how to exploit it. The effect might be too short range to be of use.

I'm not sure those are examples of dinoflagellets cory. dinoflagellets are unicellular, phytoplankton. Typically smaller than diatoms

This is definitely Dinos lol

Anyone new tried this with success?

Sorry to bring up an old post. Oddly enough- I added sea lettuce to my refugium in an attempt to grow it for my parrotfish. Came across this thread when researching how to make it grow quickly.

My sand was clean as a whistle. I had 2 fish die and it seems Dino’s flourished practically overnight. Sea lettuce was added on Sunday. 4 days in and the central area of my tank is looking a bit better but I still have quite a bit of Dino’s on the sand and rocks. Now I’m wondering if it’s related to the sea lettuce.
