I have been missing for quite some time since I have been moving shops and house, so do bare with me through this season of changes.

Any way, back to the question at hand. I personally believe that you can keep both system depending on your expertise and equipments at home. I keep my fish in both system, most in fiberglass ponds and the other in a very large pond which in itself is a green water system since I rare change the water 100 percent. Green water at it's purest form is not necessary. It is better to provide lots of sun light which will be much more beneficial for the fish with all the positive effects that green water will suppose to bring. Any one else has an openion here, you are all very welcome. GF are not difficult fish to keep. Clean water, lots of sunlight and breeze and ample good nutritions and supplements for best results.
