Dear Muske, I agree with you on the natural balance of the water. All I need is some more aquatics but they are very rear here. Bought several seeds from abroad and now I will try to grow from seeds.
As mentioned my umbrella was indoors for many years but it is ok now outside also Thalia did not face the winter yet, supplier told me that I can keep it in the water during winter, but summer was very difficult for it, although did bloomed quite alot, so much sun was too much for her.
I wonder really to see the 4 seasonal situation of the pond and next May I will allready be survived all the experiences and my knowledge will be more compact. Thanks
