Diatoms Invasion

Without resorting to chemical means, what is the best way to get rid of diatoms?

My tank is infested with these brown spotted diatoms They're making all my plants look awful <Sigh>.

No chemicals? But I have one that clears it up! I dunno, a shrimp, pleco, or more plants would clean up the mess? Otherwise manual removal.

The dreaded problem of diatoms is due to a combination of the following: nitrates, phosphates, and light. Address those issues and your problem will go away. Being the plant forum, I'm guessing your levels are high on all three counts.

Thanks for the tips. Did a 50% water change to bring down the Nitrates...do the Diatoms eventually 'fall off' from the plant leaves?

Diatoms just "go away" over time, or you could use ottos or shrimp to help speed up the process. You could also rub your fingers over the diatoms to get rid of them. I don't think doing water changes will help get rid of it, but you can definitely give it a try. It won't hurt the tank

Who would have thought that plants like dirt?!

what do u consider high? i've had 12 ppm phosphates and over 80 ppm nitrates without diatoms or other algaes at times. some have had more than that with crystal tanks.
if u have unhealthy plants then sure this can be a problem but a well growing tank with high nutrient levels wont hurt a thing or have algae explosions

Rubberlip and BN plecos, otos, and amano shrimp work, but huge water changes until the stuff disappears also works. Combine all those forces and you won't have many diatoms.

Asked LFS for diatom eating catfish......got a huge puzzled look. "Diatom?" Is that a type of flea? Then walked away pretending he was in a hurry or had something to do. <Rolling eyes>....ridiculous!
