I decided to try an idea. The container is an empty protein powder jug. I got the idea from seeing an under gravel filter push water when tank was low. It puts a vacuum on the container which pulls water in through small line on top. There is gravel in the bottom and filter media in the top portion. It’s kinda noisy might be better in a sump. But it moves about a cup of water in 30 minutes. So the jug should work to lower nitrates. I’ll test in a week or so and see. Here’s some pics and a video.https://youtu.be/Guee-0JSGhg
