With 10 tons pond running on two Vortex Chambers, the pond water finally clearing up today. The filter has been running over a period of more than one month. The bacteria in the bio chamber appear to be matured. The next thing to do is to monitor the nitrate level in the pond water. Very soon, I will have to re commission the original underground filter so that I can restart my Trickle Filter which has been idling for the same period of time. Hence, the Vortex is working well.
