Here's a little exercise to kill the winter doldrum: You have an option of choosing from one of the two ponds below. Which one would you choose and why? And no, this is not a tricky question.

Pond Option 1: A pond with total volume of 10,000 gallons, 1/3rd of total volume (~3,300 gallons) is filter volume that consists of vortex/Jmats/fluidized K1 kaldnes & biochips. This pond has a turnover rate (TOR) of once every hour (5,000 gph through the vortex/Jmat/fluidized K1 kaldnes & biochips and 5,000 gph through a set of showers). This pond also has a constant trickle of fresh water of 1,000 gallons/day (10% of total volume displaced per day). Pond Option 2: A pond with total volume of 5,000 gallons with exact filtration volume, filtration media, set of showers and constant trickle. Specifically, this pond also has 3,300 gallons of filter volume (2/3rd of total pond volume) consisting of same size vortex/Jmats/fluidized K1 kaldnes & biochips. The pond TOR rate is once every 30 minutes or twice as fast as Pond Option 1 (5,000 gph through vortex/Jmat, fluidized K1 kaldnes & biochips and 5,000 gph through a set of showers). This pond also has a constant trickle of fresh water of 1,000 gallons/day (20% of total volume displaced per day).

Both of these ponds have 10 females that are 24" average in length. You feed the same amount of 1.5-2% of total body weight per day. Pond water temperature and source water parameters are identical.

Knowing the parameters above, which pond would you choose?
