I just finished my stream and veggie pond and filled it back up (bout
4000 gallons). is it safe to put my Koi back in the pond or do I have to
treat the water somehow? I used ground water but it goes through a
filter to make it drinkable.. will that hurt the fish? I really want to
put them back in.

Thanks
Mike

Well water is low on 0xygen so it is good if you have a waterfall or a
fountain to get some Oxygen in the water. I always make sure I spray
the water in the pond to Oxygenate it. It probably is safe to put the
fish back in if you are not over stocked. Happy water gardening.
