I am looking to start stocking my 220 that is being filtered by FX6. I was wanting to stock with 5x Bala Sharks, 6x Denison Barb, 5-7x clown loach, and 20x tigerbarb. I feel this may be overstocked. AQ advisor rates this at 134% stocked. What is the public opinion and should I add additional FX4/6?
