I have read that you shouldn't keep bio balls with live rock. It is my understanding that is only the case if you have 1-2 pounds per gallon...enough to support the tank. My tank is only 50 gallons. To me it is still fairly pricey to fill with enough live rock. What should I do if I only want to keep 10-15 pounds? Keep the bioballs?
