HAHA! I just ran a check on the water params of the L200 tank, and with all those big beasts, and the 4 sailfin mollies, and the hydro gar, and the 100+ con babies, readings were ammonia 0.0, Nitrite 0.0, and nitrate 0.0! Good stuff. Hopefully that will stay at that quality. I have two seperate bags of purigen that were placed into the filter at different times so when one was exhausted it could be pulled, and the other could still work. Temp is sitting comfy at 82F, and hardness is 9dKH, and 9GH. pH is sitting at 7.0. Good things good things.
