On the evening of 13 August 2019 (Tuesday), my 1,000-gallon watergarden was a bit low on water. So I took the garden hose and placed it in the watergarden and turned on the water. I intended to turn off the water in only 10 – 15-minutes.

I went inside the house and started doing something else. I completely forgot about the watergarden. A couple hours later, I looked outside and noticed one of the water spouts (underwater pumps) wasn’t high like it’s supposed to be. I then remembered I forgot to turn off the water more than an hour and a half ago.

I turned off the water. I accidently added approximately 200-gallons of tap water to the 800-gallons of freshwater already in the watergarden.

I accidently added 200-gallons of tap water, chlorinated tap water to 800-gallons of freshwater. I was hoping the chlorinated tap water, even though it was mixed with 800-gallons of freshwater wouldn’t hurt the 50+ koi fish. Turns out that chlorinated tap water outright KILLED 06 of my koi fish. I’ve had these koi fish for several years.

These 04 koi fish died within hours of adding the chlorinated water.

These 02 koi fish were found several hours after I found the first 04 dead koi fish.

According to www.aquanswers.com, 2ppm (2 parts per million) of chlorine from tap water will take up to 04 ½-days to evaporate from 10 gallons of standing water. They go on to state that ultraviolet light, circulation and aeration speeds up the evaporation dramatically.

Since I found the dead koi fish, I’ve had the 03 filtering / aeriation pumps going 24-hours a day so to evaporate all possible chemicals. Now going on 04-days non-stop (evening – 17 Aug. 2019).

Here’s my point to all this. Tap water is loaded with chemicals like chlorine. We humans drink tap water. It won’t kill you real super quick like it did with my 06 koi fish, but what do you think it’s doing to you in the long-term?

Can chemically treated tap water be linked to:
• Degenerative diseases
• Heart Disease
• Cancer
• Alzheimer’s Disease

No doubt, chlorine kills bad guys in the water so it’s ‘drinkable’, but what is that same chlorine doing to your body – very slowly?

Me, I stopped drinking straight tap water many years ago. I only drink filtered water or bottled water that’s proven to be filtered and absolutely chlorine free.

Let me put it to you this way. I’d rather drink a tasty super sugar-laden Mountain Dew than straight tap water. With all that sugar and other stuff in a tasty cold Mountain Dew, I figure tap water is more dangerous to your health.

Note:  To insure this deadly mistake doesn’t happen again, I purchased a 05-gallon water bucket dedicated solely for adding water to the watergarden, 05-gallons at a time when needed. If I forget about filling the water bucket with water, no problem, the overflow is going into the ground and not the watergarden. 05 gallons of water mixed with 800+ gallons of freshwater won’t hurt my koi fish. But as you just read and viewed, 200-gallons of chlorinated water even diluted with 800-gallons of freshwater KILLED 06 of my koi fish within 12-hours of being exposed to the chlorinated water.
