No Harmful Ingredients

By harnessing the power of nature through compounds in organic plant-waste, we're able to provide healthy, renewable alternatives to toxic chemicals and high-stress problem solving in your tank. It’s time we start working with ecosystems instead of against them. 
We know how water ecosystems balance & regulate algae, so we bottled key compounds to support your aquarium's ability to do so on their own.
Our products are manufactured in our Seattle facility by recycling local, organic plant-waste that would otherwise end up in a landfill
