I’ve used Sera Alder Cones for several months in my black water tank. The water turned dark naturally, and my cichlids seem more active. No fungal outbreaks since I started using them. A reliable and effective product.

The cones work well to lower pH and create a stable environment. My fish have shown better spawning behavior. I noticed the water color change after a week of use. Slightly expensive but worth it for the results.

Great product for maintaining a natural black water setup. The cones dissolve slowly and don’t cloud the water. My tank has remained healthy with no signs of fungus or pH spikes.
