Can Baker's yeast treat a Diatom outbreak?

[L8Braker]

Ok so I just put in the last dose (3rd one EOD). While the diatoms on the glass/sand didn't just disappear yet they certainly appear to be going away. I wound up cleaning my glass and sand last night (have guests coming over) so the true test will be to see how quickly they come back if at all now.

No, because diatoms go away on their own. You have no control group.

this couldn't be easier to test, just put some of the yeast in a pint of rodi water with a 1/8 teaspoon of sugar and wait for a few days. Do the same using tank water instead of rodi in another container. See if they come out different.

I was a baker, salt kills yeast. Also, diatoms aren't even that big a deal. Also, I like when people start threads asking questions and then call people that disagree with them names. That always turns out so well.


Prove that statement

First of all - salt in high concentration kills yeast...

And who knows, maybe the process of killing the yeast (if saltwater indeed does that) is what makes the diatoms go away... we have no idea why it works.

And as far as proving anything - did you read the thread?

Everyone who has responded that has done it says it works.

The owner of Vivid Aquariums - very respected in his hobby - says it worked on ALL of the tanks he has tried it on.

So, again, everyone who has responded and done it says it works - the only naysayers are those who haven't done it.

I have been thinking about trying rhis as well but I can't figure out the dosage. I have a Nuvo 10 and was thinking just a few pellets at a time. Also, does it have to be that brand and rapid rise? I have bakers corner active dry yeast now. I could pick up the rapid rise as well.

No just a bakers yeast try 3 times in seven days add a pinch like puting salt. But not in the main tank because the fish will eat it .

Did my first dose yesterday. I'll update later this week with any results.

Well... that is a hard one - using 1/4 teaspoon to 400 gallons...

As far as if it has to be the Fleischmann's RapidRise Yeast - no one really knows - that is the only one tired so far I think - and we know that one works.

If you try a different one - let us know the results.

I used the yeast you find in super market... it worked

Good to know!

 

[gguirola]

Any Updates on your tanks? I am just wondering what were the results before and after because I want to do it too.

 

[waynefish]

I tried this over a week. No difference for me. MB7 is helping though

Didn't help for me either. Some spots actually got worse during treatment.

Are you sure it was diatoms?

I linked this thread to a new one in the Reef Chemistry Forum and everybody over there says it can't work. Yeast has a low enough tolerance to salt solutions that in a saltwater aquarium the yeast will die very quickly. Personally, I'm not buying it either.

I want somebody to explain how or why it works. Without a scientific explanation, it's just a anecdote, a story with no foundation.

I guess I am one of the naysayers :spin2:

Anyways the question is, is the yeast actually doing anything here or is it the substance the yeast is encased in that is doing it?

Personally I brew beer and make my own wines and I have a hard time believe it is actually the yeast doing it, especially bread yeast. Bread yeast is easy to kill off compared to a champagne yeast or turbo yeast.

this couldn't be easier to test, just put some of the yeast in a pint of rodi water with a 1/8 teaspoon of sugar and wait for a few days. Do the same using tank water instead of rodi in another container. See if they come out different.

Prove that statement

I read about this many times over the years and never believed it either. I also believed salts in the seawater would quickly kill the yeast.

Yeast would also become a good food source for many other nuisances as it contains a good amount of phosphates. Thats about all I saw yeast good for.

However, I was fairly surprised when I decided to put it under the microscope. It certainly reacts in someway with diatoms and specifically diatoms.

I don't know what this means but here's what I saw and posted in another thread

1/4 cup water, 2.25 teaspoons active dry yeast, .5 teaspoons sugar. Water temp 73F.

Left is rodi and right is saltwater from tank. 20 minutes in.

Diatom brownish before yeast

Diatom green after yeast

Agree and IMO diatoms are the least to worry about compared to other nuisances that could come out of no where even in low nutrient systems like cyano, bryopsis, and dinos. Normally its watch your source water and wait. I feel diatoms are important to our tanks.

Yep, that was saltwater pulled from my sump. There was not as much of a reaction as the freshwater sample but it did much better then I expected. In cooking you avoid adding salt to yeast. Which this does show it did "flatten" the growth.

Are you sure it was diatoms?

I haven't put it under a microscope, but I'm almost sure if it. I have been thoroughly cleaning the sand every week and it has been helping. At first info moved the sand it would cloud the tank and now I can blow most of the sand with a turkey baster and get minimal clouding.

Welp, I'm giving it a try on my 120g. Just a sprinkle a day...

Please post your results as I am sure there are many people like me who are strongly considering this approach regardless of the naysayers who would rather discard the idea vs perform some real-world research.
