    Hi all, was trying to clean my planted tank's surface but encountered some tiny spot of algae look alike stain which can't seem to get rid of, even by scrubbing it. Any idea what are those stain and how to get rid of it?

    Thanks!

    Please be careful with the scrubbing, you do not want to scratch your glass tank. As for cleaning the algae try to use a soft sponge to remove it.

    You get try getting nerite snails. They do eat the green spot algae. And it is quite fun to look at them slowly scraping the algae off.

    sorry, can't really take a clear photo of it to show everyone.

    yes, it is green in color. i did use sponge to try to remove it.

    is green spot algae that stubborn? only nerite snail is the solution?

    In my experience, nerite snails only good for those brown algae on your tank glass, if you can't get it off with a sponge, chances are, nerites won't either.

    You can try using a razor blade as a last resort.

    I kept 2 zebra nerites and 5 horned bumblebee nerites in my 3ft planted tank. They eradicated any green spots algae that I have on the glass and on the anubia leave. And they look very neat too, except that my 2 zebra nerites eventually escaped from the tank and was found dried up under some furnitures.s

    Have you tried using a plastic card (like ATM card) as a scraper?
