Hi Jeff, Wow! It sounds like you are making excellent progress. The Turface cloudiness should be substantially reduced in about 4 hours or so with good filtration, mine was about GPH @ 5X tank volume. I think it took overnight to get really clear. I did not use a 'water polisher', just poly fill and bioballs. I did "seed" my filter with some "used" polyfill to give the nitrogen cycle bacteria a head start. What type/size filter are you putting on that Monster Tank? Keep us posted on your progress! Glad to hear that the Nymphoides sp 'Taiwan' is doing well for you. It is a great plant and grows well for me in Turface, even without CO2.
