Cascade Koi & Aquatics have sold NT Labs products for many years and we stock of the products by NT Labs across the range. NT Labs Liquid Co2 Boost is suitable for coldwater & tropical aquariums. A source of carbon for plants to thrive allowing them to outcompete and actively combat algae. All plants need carbon to grow. Aquatic plants obtain their carbon through CO2 dissolved in water. Liquid CO2 Boost gives aquatic plants a source of dissolved carbon without the need for expensive equipment such as CO2 gas injection. With Liquid CO2 Boost, plants will grow more vigorously, removing algae-causing macronutrients such as nitrate and phosphate. For extra luscious and vibrant plant growth, Liquid CO2 Boost should be used in conjunction with Plant Boost. Plant Boost is a rich all-in-one plant food which provides all the trace elements used by growing plants especially iron, magnesium and potassium.
