Nitrate in a dirted
My girlfriend ended up taking my 10g tank that I was going to tear down.
We rescaped it with dirt capped with pool sand. It looks awesome. That was about three months ago (mid September). We used the same canister/bio media, and haven’t had any issues with Ammonia, or Nitrite. However, the nitrate has been through the roof.
I understand that’s a result of the dirt and the BB doing their jobs.
But we do 25% water change every two days, and the nitrates still sit at 80ppm.
The growth has been awesome, and don’t have any issues with algae. (We had some diatoms, stag horn, and cyano, but they all passed on their own)
Should we do anything, or just wait it out?
I’m think increasing the lighting time might encourage more plant growth, which will lower the nitrates.
