What about sewage disposal? That's a problem with long term living on houseboats. Most septic systems tied in would drain into the pond.
Crazy story. So back in the 60's there was this lake in BC that was huge lake trout lake. There was lots of other fish in the lake walleye, perch, small and large mouth bass. The lake was well known for its lake trout. In the 70's and into the 80's they stopped allowing the houseboats on the lake system.
It only took 10 years and the eco system crashed. The lake trout were the first to go.
It seems that the few houseboats on the lake were adding just the right amount of phosphates and fertilizer to the water to feed a great plankton bloom for the young hatch-lings.
Long story long..... don't be afraid of a little grey water in the pond. Just like fertilizing a pond don't over do it.
Cheers Don.
