Walstad tank, water RED!
I set up a Walstad tank (top soil topped with gravel) and the water is red. Like dark red. Like wine. It's crystal clear, but DARK. Water changes help for a short time, but then it goes right back to red.
The tank has fully cycled now, but the red is driving me crazy. Charcoal in the filter doesn't seem to be helping. Anyone have any ideas on how to get what I'm assuming are massive tannins out of the water?
