Alder Cones (1/2 - 1 inch)
These pH-lowering alder cones are a great alternative to cholla wood. They are just as practical and aesthetically pleasing as the driftwood, and serve some of the same purposes!
These miniature pine cones make a charming decoration in any aquarium, but they also serve some very useful purposes. Like cholla wood, alder cones are a fantastic and natural way to lower and buffer pH. We use alder cones in many of our low-pH tanks because they produce ideal water conditions for acidic-loving animals. They also release tannins that help prevent fungal infections and fight bacteria in aquariums. The cones add a natural beauty to any aquarium in which they are placed, and dwarf shrimp particularly love to graze for biofilm on the surfaces of the cones.
