Question: Sera Black Water Conditioner?

[Dyelon]

At the pet store I work at we started selling a Sera water conditioner that makes the water black water I believe it contains tanic and humic acids to change the color of the water like a piece of driftwood would. I was wondering if anyone had used it with their axies just to make sure it is safe. I like the way it makes the water look and I think it would make them more comfortable when the lights are on. Any opinions?
