Help! High nitrates

by Zachary Kittle

I have recently set up a new dirted tank using earthworm castings. The tank has been cycled but I having issues with high nitrates. There are no fish in the tank. Just plants and some snails. I'm wondering if the earthworm castings are leaving something into the water column. Any suggestions are welcome.

    Adding worm castings=nitrates. More plants and water changes are a solution.  How high are nitrates? How many plants do u currently have? Drop in on chat and we may be able to give more detailed advice once we have more information from you.
