ok so we have decided to just keep the size pond we have now and then add to it if we feel we want more next spring/summer (which I'm sure we will) But I've done some testing on my water from the spring and everything has turned out to be absolutely right where it should be. now here is my problem..the temperature unfortunately is only around 50-55 degrees? from what I've read this is too cold? Am I right about this? And if so is there anything that I can do to help this? I dont have electric run to my pond since its all natural but I have been doing some reading about solar powered heaters? any advice will be extremely helpful!! I am totally in the dark about everything ponds other than what I've been learning through the internet and on here. but I am super excited to get my project underway and done!!
