A sufficent amount of plants will filter the water.
The surface was covered with slavinia until yesterday, when I took about half of it out so I could see the fish
I only have a powerhead in there for water movement.
Have you had any probs with the danios jumping?
Thanks. I haven't noticed any kamikaze danios, but it's not like it would be easy to notice. Normally the water is about an inch and a half lower than it is in the picture, but it rained this morning.
