i built the reactor and it is amazing. Puts my tank to 30ppm in less then 30mins. Few questions though, i have it inline with my filter and dont have any adverse flow rates. If i rebuild it with bio balls will they 1)try and float to the top and also get tumbled around? 2) slow down the flow rate?

Also anyone have any extra clear tubing leftover they would like to sell? 12+ inches if possible?
