Diatoms and yeast dosing?

I see this was posted on facebook. The image used with this thread was Fleishmann's Active Dry. I thought it was the Rapid Rise instant yeast?

Isn't the difference between the two glucose and non glucose?

I guess from what i've found, the Active Dry is larger granules and should be dissolved prior to 'baking'. Maybe there isn't a difference?

From reading there is not much of a difference. They are all of the Saccharomyces cerevisiae yeast.
What caught my attention is that salt will inhibit the growth rapidly of these single cell organisms.

On vivid aquariums YouTube page he says it's the rapid rise in the comments.

That doesn't surprise me. What surprises me is people saying that it works. So, it boils down to yeast per water volume. Possibly? Or is it just coincidence?

I will head to the store today to grab some yeast.
I will get going on this as soon as I can

So if this is from the sugar in the yeast is this considered carbon dosing?

If so should it not be used if your already dosing a carbon like vodka?

I have not found evidence that there is sugars in yeast

OK I thought someone said prior there was ... so its safe to try when dosing carbon I'd assume

Check out the nutritional values of bakers yeast



That is per 100 grams

People are making all kinds of claims.

I tried this yeast method for 2 weeks. My diatoms never went away and a cyano bloom grew stronger. If it were like carbon dosing, I would guess my phosphates should have lowered? Where they did not.

Been battling diatoms for long time hope this works with no ill effects.

How long is a long time? How long has the system been running? What is your source of water? How often do you do a water change? How often? Are you sure it's diatoms?

Looking at what twillard posted yeast has a lot of phosphates and other trace elements that cyano would love to absorb. Looks like a good food source for cyano, dinoflagellates, etc.

Keep in mind that is per 100 grams lol

Some also said there corals loved it which would explain the massive amount of potassium lol

Yeast consumes sugar and produces alcohol and Co2 as a byproduct. That's how freshwater planted tanks use it in DIY C02 setups, vent the C02 into the tank and then discard what is essentially prison hooch when the yeast is done breaking down the sugars.

percent's a percent though. Looks like many organisms would like it.

Yes, in baking it will hinder the yeast. Salt that is. Which is why I was questioning it's effectiveness in saltwater other then becoming a food source. Which it could still very well be a food source. But saltwater may have slowed it down but certainly did not stop it or kill it with in the couple hours I was observing it.

Very true. Maybe one day we could dub this Sea Crack? Sea crack is wack, but cheap! I was down less than $3 trying this, but i'm down $30 purchasing GFO and other things to combat my issues at hand. However, I don't have legit proof yeast was the culprit.

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.
