prymnesium parvum

[GT3000XX]

Has anyone had any luck treating prymnesium parvum algae? I scoped a sample and that is what it is. I can’t find any info related to treating it in a saltwater aquarium. Thanks

Possibly a strong UV light? (trying to avoid chemicals) :)

Algae are primitive, mainly aquatic photosynthetic organisms that contain chlorophyll and lack true stems, roots, and leaves. Algal blooms (an explosive increase in the population of algae) are common in aquatic environments, and harmful algal blooms (HABs) can cause substantial problems to...

I have the same issue, covering my glass within 3 hours! Let me know if you find any info, struggling!

Have you managed to treat or fund out anymore on this?

No I haven’t. I ended up tearing down the aquarium.

Oh wow

It was just a 30 gallon reef. I still have my fowlr aquarium.

I don't have that many corals in my tank right now so I decided to start dosing vibrant so far it has slowed the growth on my glass and pumps.

Any update on your battle with prymnesium parvum?

I thought these be wanted when you have dino's and dosing silicates, I mean wouldn't we want this instead of dinos?

 

[Reefrats]

Struggling with this too. It accumulates on the water surface and the glass. Has anyone found anything that works?

Can anyone post pics of this ?

I've been battling this stuff for a few weeks now...it's only on sand bed...been utilizing a UV Sweeper every other day followed up with bacteria dosing on the off days...I've been using a combo of Microbacter 7 and Microbacter Clean trying to replace what I'm killing off The UV Sweeper has been pretty effective but feel like it's short lived...I plan to change up bacteria and move to Rebiotic. It has been suggested to me use H2O2 at 3mls every 10g...will be my last resort - nothing in the tank seems to be adversely effected by them...they just ugly

Interestingly, I just found out that I have Prymnesium parvum as well. The symptoms, including snail deaths, clam deaths, corals mad, water params fine, presence of diatom-like dust on sand, glass, rocks, smelly smell, all check out. The pics from under my microscope also confirm.

At this point, I guess I will try UV and GAC. If that doesn't work in a month or so, I will probably restart the tank.

Lemme know how things go with the uv for you...still battling away here - heard of a guy who beat it out with LifeSource dosing - have just done a second dose - not optimistic but maybe

Yeah, we will see. It's interesting that you aren't having any negative impacts from these things. My corals are sort of opening up now after almost two months of being closed up. Hopefully things continue to improve. It's also interesting that you have only found yours on the sand bed. I have looked at scrapings from algae on the glass and it is full of these things, though they *might* not really be very alive on the glass. They don't move much.

I have done two doses of AF LifeSource already. It might be part of why my corals are opening back up, but maybe not.

I have seen the same in terms of movers and non-movers in the sand bed...trying to figure out their "life cycle" not sure if the non-movers are cyst stage or dead stage...I do have a small pocket of it on my glass but not a large spot - in terms of corals the only thing I can note is zoas some days half will close up and re-open the next so not certain the PP's are to blame - the rest of my tank - mixed sps and lps are fine and actually thriving - all fish and inverts are good as well...I should have recent ICP results back at the end of the week or early next so will see if anything crazy off there .... will def keep the thread here posted...good luck on your end
