Jelly like algae

[Gaoweihd]

Hi reef community,

Can anyone help me to identify what kind of algae is this? It’s transparent, grow on the rock and hard to remove. They’re everywhere in my tank

Thanks

Hard to tell without white lighting but I’d say it’s a sponge myself.

Not sure what you've got here, but I'm happy to give you a bump.

bump, they're still all over the tank, I'm about to give up and break down the tank

Sorry for the slow responses here - have you broken down the tank? Any chance you could get some microscope pics of the stuff?

That's under 100x microscope

I found a few posts and non of them have cure of it, I guess I'll take down the tank

The best I can do is ID at this point that it's from the taxonomic class Pelagophyceae - it's likely a species like Chrysophaeum taylorii, which forms colonies in a mucilage sheath and has blooms that smother other benthic species. Unfortunately, that's not very helpful at this point, but it may be a good starting point for people who have this issue in the future.

the photo of Chrysophaeum taylorii I searched online looks exactly like what I got in my tank, is there any known method to eliminate them from the tank? They've been in my tank for 1.5 years, I've tried low nutrient, high nutrient, blackout, high par, etc, none of them works. they grow like crazy.

I'll try that when I have time

If it is C. taylorii, they have found that high flow ("high hydrodynamics") decreases both its cell density and mucilage production (so it doesn't like high flow) and that high nutrients ("nutrient enrichment") increases cell density but decreases mucilage production (I interpret this to mean that it'll produce lots of cells to try and reproduce - since it reproduces pelagically - but it will decrease its growth).*

So, in theory, you may be able to reduce/remove it by blasting it with flow and raising the nutrients substantially (obviously, these would both be risky ideas with corals), then maintaining those conditions for an extended duration while using a skimmer and frequent water changes to remove the majority of the cells produced - in practice, the results may not be so good, but it may be worth a try if a tank tear down is the other option.

Thanks, I'll give it a try.

Thanks, I'll give it a try.

Let us know how it goes!
