First let me thank everyone for all the help and comments when my fish were dying, whatever it wss seems to be under control now. I've been checking my water and it's fine now, but i was wondering i never had added pond salts to the water , and when i was having all the problems the pond store i deal with said i really should add them, is that something that needs to be added, and since i haven't added it before what does it do to the fish? I have 5 fish left and today i saw 3 very tiny tiny babies! Was really glad to see them, I've never seen them before when they were so small it was very cool to see. I've always seen them when they have gotten a little bigger. I want to make sure the pond water is as healthy as can be , thanks for any help.
