You're still gonna lose an inch a day or more.
and if it doesnt , you have a severe problem.
Here is why.
You don't have a water well.
My question here is " why would anyone have a lake or pond without a well? OR shed........OR both?
I know that people do it and count on the weather. And this is what happens when THAT happens.
Pardon my sarcasm.
If your pond doesn't lose water ( sealing it like a swimming pool) that yew cant replace, then sir, you will have a pond full of nitrates at some point. You will need to use sunlight and oxygen/ aeration and that still might not do it, given fish population crapping all over the place, and the build up, IF you're feeding them , it gets worse. You have no outflow/ discharge) to empty all of that out. And nothing to flow it out.
About now they are living in muck. They will not grow.
Plus you have an 1/8 pond?????????? And you have open water swimmers like HSB???????? The smaller the pond is , especially in your case, the more water it will lose ( think . You're over stocked, You cant possibly keep these fish fed and healthy. Sealing and never losing a drop of water is not the answer. There's even more to it than this. Like PH balance.
The list goes on .
None of this is easy......or everyone would be doing it.
I'm apologize for not sugar coating this.
this is what you need to know.
Of course there was a fish kill.
