Can Baker's yeast treat a Diatom outbreak?

[icedgxe]

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

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.

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

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.

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.

Any updates????

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.

Day 1 after first dose.

Any new updates? What brand of bakers yeast did you use and what amount for what size tank?

[Lowefx]

I didn't update yesterday because I did a 20g water change, sucking out most of the dinos. I will do another dose tonight and continue for a few more days. I have not noticed a change within the first 2 days. I'm using Fleischmanns rapid rise instant yeast. Right from the grocery stire. It's hard to guess a measurement, so for my 120g tank, I'm using the size of a nickel in my palm when I add it to the tank.

Why add the yeast and then do a water change? I would assume that you would want the full dosage of yeast to remain in the water to do its magic.

Exactly.

And the dose and brand are in post #27 in this thread.

Thank you. Have you tried this yourself?

Because it was time for a water change, and it will help rid the diatoms. But after 2 days I still show little signs of diatoms again. You should try your own experiment rather than trolling me. I will continue my dosing for only a few more days because I'm going on vacation in a month, and I want my tank completely stabilized before I go. As of this time, I am not noticing any changes. I am also running a ulns Zeovit system which may play a factor. Good luck, and let us know what you find out.

For those that have tried this, did you turn off your skimmer and/or UV?

[Lowefx]

I do not have a UV, and I left my skimmer running. There was extra skimmate but nothing crazy. I'm going to test again after my vacation.
