How to keep a tank without plants?


I am trying to setup a tank without plants, 30G.

But if I don't have plants, algae starts to grow because of the light.

How do I make a tank without plants successfully without the algae?

Use those lights that come with tanks at big pet stores

Is there a specific reason you don't have plants in there?

If it's a setup/maintenance issue, you could throw in some floaters or something like elodea that just sits loose in the water column.

Otherwise, I imagine frequent water changes to keep the nutrients down, low light, and some snails

Or leave them on for less time... I had algae issues until I put every single aquarium light (on 5 different tanks) on a timer.. I wasn't very reliable at not leaving them on too long.

If you're not keeping plants, then you don't need to use the canopy lights.

The ambient light from the room or window (not direct sun) is good enough.

Then you can just turn it on when you want to see the fish.
