blackwater extract

[barracudauk]

I use Kent black water with my high fin wolf fish. She goes mad for it and on occasion she has knocked it out of my hand before Ive managed to pour the dose in. I am in a hard water area, the PH in the tank is 7.5. I have not measured any change in PH or had any issues with algae.

I use Ketapang Vital in my tanks. It's not as dramatic as actual blackwater extract but I swear by it.
