Hi
I planning out a pond for my turtles and one of my problems is working out the filtration.
My first option is a filter I have it worked out but my problem is a filter big enough for that body would require a large pump. I can get it but it's quite expensive.
My other option is to not have a filter. I have been lucky enough to have a large spring near my house which I can use. It was suggested to me that I could just change the water cause I have access to a practically limitless amount of water. Problem is it's hard water.
So that's my situation.
Thoughts?
The pond will be 900 liters btw
