Hey all, I have been battling diatoms for quite some time now. My LFS told me to use bakers yeast. 1/4 teaspoon for 400 gals. I have a 100 gal tank so I should dose 1/16 of a teaspoon every 3-4 days? Should I just add the yeast in the water or should I dissolve it beforehand? @Randy Holmes-Farley do you know how bakers yeast combat diatoms?

I have a 35 gallon and used a pinch of yeast twice. No more diatoms. I just dropped it in the top and it did the rest.

@Alexreefer did you continue dosing/feeding yeast? If so, what have you found to be the most positive and/ or negative effects of doing so?

I have stopped after a while, Diatoms are not present, and tank is doing good. Dont see any negatives

How long did you dose for and what was the amount you settled on?

So are you saying that yeast worked to get rid of your diatoms?

I don't see any strong reason to think this will work to deter diatoms. Removing silicate sources is my general recommendation.

Some folks think yeast helps, but there's no clear mechanism, so no clear understanding if it works sometimes or it is just coincidence.

here's a lengthy discussion tracking someone's experience with it.

So let's try some yeast!

So I've been trying to eliminate a small diatom infestation on my sand bed for the past couple of months to no avail. It's persistent and will not bend to my will, no matter what I try. Vacuum the bed- nope. Blackout - nada. Increased water changes - not a dent. GFO - laughing at...

"The verdict, at least for me was it worked. It wasnt overnight and didn't completely eradicate them in total, but did drive their numbers down significantly. The rest was time and good husbandry. I would do it again if needed."
