I added water lentils on top which should help with nitrates and such, my main worry is that I don't know how to keep the water stone in it since it pushes them underwater but with a single fish and plants I think oxygenation should be fine?
Mhm! Labyrinth lungs and all. I just didn't realize how fragile water lentils area until I saw them spinning wildly inside my tank due to the filter's 'fountain' and the water stone's bubbles
Well, I only have a spoonful so far (they also gave me a HUGE bag of water from their acquarium at the shop to help settle mine so I think that's what helped kickstarting the cycle much faster?)
(It is also worth mentioning I'm still learning, i'm glad to learn where bacteria is and I guess you're right, the water lentils totally brought it in. Probably)
