Here’s another video in the Krzysztof series. This absolutely incredible tank uses zeovit and NP Reducing Biopellets. Flow is provided by 2 Tunze Turbelle Stream 6105, two Iwaki MD 55, Red Dragon 8000 l/h as a main pump. Calcium and alkalinity are maintained by dosing two-part using a Grotech Tec III. The tank is about 200 gallons, with a 75 gallon sump. We’re pretty sure we don’t need to say anything else. Enjoy!
