For the purposes of an upcoming article, I'd like some input from forum members: 1) what's your tank turnover (how much water goes out and comes back in per hour + how much is just moving around or circulating but not necessarily going out and in = total turnover)? 2) what's your size of display tank? 3) what have you got in the display tank that led you to decide on this particular turnover rate? 4) photos would be nice too.... 5) are your tank inhabitants doing well with this rate? Thanks!!
