ok, did a nitrate test after getting rid of my sand and doing a 75% water change. looks like the sand was a freaking nitrate factory! before, even after doing a big water change my nitrates were in the blood red zone. its hard to distinguish the colors, but id say in the 80ppm range.
today the color was a lot more orange, id say about 20ish. tap water on the left for reference, which is about 10ppm. so hopefully now that the tank is bare bottom the drip system will help keep levels low
