Options for Combating a Dino Outbreak

[Dan_P]

Scientific or not, I would like to know how many have really succeeded in defeating dinoflagellates with competitive methods. I am not questioning it.
This is similar to human medicine where it is almost never enough to just introduce a good environment in the first stage, though it works as a prophylactic agent.

Could we have a thread here or elsewhere where we have some sort of results summarised regarding how different methods and their success rates perform? It is very hard to see that in forums where the threads are long and hard to get an overview

Agree^^^. Though I am questioning the success of the methods.

I would start dosing microbacter clean or microbacter 7 along with vaccuming the Dino’s up. The bacteria will prevent the Dino’s from growing out again

I am not sure what your point is.

My point is almost always "more reading" or something along those lines.

Diatoms have been found to generate substances that seem to squelch dino (and possibly other phyto) blooms in the wild.

Diatoms have been shown to produce and release a wide range of secondary metabolites that mediate interactions between individuals of different species. Among these compounds, different types of fatty acid derived long-chained polyunsaturated aldehydes (PUAs) have been related to multiple functions such as intra- or interspecific signals and adverse effect on the reproduction of marine organisms.

Of course there's more....some of it may be familiar already, I don't know:

This week, I got a new dino outbreak in my new 250-gallon tank after dosing chemiclean for Cyano in the sand. Honestly, I’m not even scared of them anymore, and I'm happy about them replacing the ******* cyano. I’ve battled pretty much every common type of dino in my tanks: Prorocentrum, Amphidinium (small cell and large cell), and Ostreopsis.

Keep phosphates above 0.1 ppm, nitrates above 10 ppm, and dose silicates. And I mean A LOT of silicates, and they'll go away shortly.

In my previous 70-gallon tank, I think the recommended dose was something like 1 ml per week. I was dosing 10 ml daily for close to a month. Now, with the 250-gallon, I’m dosing around 30 mL daily. The only things I’ve noticed from dosing that much silicate are the dinos receding and a lot more sponges growing. Nothing else in the tank seems to be affected.

Interesting possibility, even tantalizing, but speculative, and circumstantial. How much of this substance is actually produced by which diatoms and is it produced in aquaria?

Finding information in scientific studies and then using it to support an idea is a popular approach used to sell bogus health care cures.

Now I'm not sure I see your point.

Is your point to stop reading and stop problem solving in the hobby? That would be hilarious.

Maybe your point is that the major science journals are merely sources of fraud? That would also be hilarious.

I love humor!

Getting to the discussion...

Folks with dinoflagellate blooms that don't respond to ordinary control measures are experimenting more and more with dosing silicates.

Their hope is to produce a diatom bloom that will (maybe among other things) generate some substance(s) that have a desirable effect on their dinoflagellate bloom.

That very thing has been noted to happen in the wild and in laboratory experiments.

The question is will those findings and experiments translate to the home reef tank?

Not everything does – not by a stretch – so it's a necessary question.

Nobody is expected to have a ready answer to that question, BTW.....I don't think there is an answer yet. Hence all the experimentation going on.

I wonder if anyone will refine the experiment to get better results?
