Awards and Judge Comments

While your tank is a little "wild" looking, I think you have succeeded very well in doing exactly what you've set out to do. Your tank is healthy and attractive, and clearly appears to be a comfortable home for a collection of lovely discus.

Additional Information
This tank and aquascape were designed to provide a visually pleasing planted environment for discus, while still requiring relatively low maintenance. The plants, fish, crustaceans, and systems supporting the tank, all work together to keep tank maintenance requirements low - currently one weekly 45-60 minute maintenance session. Multiple, small, automated water changes each night yield an equivalent of 50% water change every 3 days. Three tank outflows are plumbed thru the bottom of the tank, with two returns over the top. Pre-filters on outflows and return nozzles are obscured by plants. No equipment was removed for photos. CO2 in-line injection with Mazzei venturi. CO2 kept at 45 ppm by pH controller. Daily micro fertilization with 9 ml ADA Green Brighty Step 2. Potassium dosed to keep tank at 25 ppm at the beginning of each day (prior to uptake). Nitrogen and Phosphate are found in the tap water used in water changes, keeping the tank at 8 and 0.9 ppm respectively. Neither is dosed.
