Here is the sump/ algae scrubber I am planning on building. What changes should i make? It is going to be in a 30 gallon tank and the display tank is 110 gallons. It will hold a Fahaka Puffer that is currently 4 inches long. I want to get everything estabilished so it will grow with him. I want to keep nitrates as low as possible and until he gets bigger do only 1 50% water change a month or less. This will have about 320 gph going through it. and its going to be freshwater. I am planning on starting off with just the aquarium light and when its obvious it cant handle keeping nitrates low then I will upgrade.
