If you really dislike it, you can use a toothbrush or sponge to scrub it off.

I'm of the opinion that it looks good in a shrimp tank, though, and ends up being okay if it's just on a few areas of hardscape like that. Never lasts very long in any my shrimp tanks, so it may be something that disappears relatively quickly for you.

What's your lighting situation? Cutting that down a bit may help eliminate it.

Thanks! Know I can clean it off with a toothbrush... I'm just wondering if I should? I may leave the hardscape & back glass a little green and scrape the sides down? It is good for the shrimp. I have a Fluval 3.0 on there at 40% max at it's brightest for a total of 8 hours.

How long has the dust algae been present? Just a few weeks? Months? If it's been longer, has it spread beyond the rock and glass to the point that it's a hassle for you?

If it's been going on for an extended period of time, combined with your dislike of it, it could be a good idea to explore mitigation efforts. But if it's a relatively new thing and you're okay with how it currently exists, it'll probably be fine to leave it.

I like the way it looks, so take my point of view with a grain of salt for sure.

About a week to 10 days maybe. I'll leave it and maybe try scheduling the lights for 7 hours.

What kind of snails do you have in the tank, if any? They tend to make quick work of this sort of thing as well.

Bladder snails for the most part. Not as many as other tanks, because there are sooo many shrimp here.

Really like the way your tank looks and being able to see so many active shrimp is great.

Thanks. I really like it too. I was inspired by a YouTube video. Other than the substrate behind the rock it was all stuff I had on hand. I pulled the two pieces of Valisnaria from the front yesterday and moved them to the back.

Pick up some snails or lower your light duration or intensity. You have slow growing plants. You might run into GSA/cyano down the line since your lights are strong but the plants are slow growing.

I'm not as much worried here about how to balance the tank and remove algae as I am with whether I should since the shrimp like to eat it.
