No Rain

We have a few episodes of dark heavy clouds and then it clears.  No rain for a couple of weeks and my rain water storage is running low.  It is hard for me to scope out the water!  I hope the rain comes and replenished my water tanks and also I need to change the water in my pond before I put in fresh fishes again.

Over the years, this happened once while I was travelling.  All the fishes died.  So I change the water and start all over again.  I suspect it was our weekly fogging.  So I put a plastic shield and it worked for many years.  Now I am not sure it is the same issue.

I just have to replace the water and start all over again and see.
