Help! Left hose on overnight!

[Jennifermariar]

I cannot believe I did this! Never thought I would since i am always careful to set an alarm! But it happened, and I left my hose running for 6 hours. I ran out and turned off the water, dosed a 3x concentration of prime safe to neutralize the chlorine. But I already lost my youngest koi and while they are no longer all gasping at the surface, my koi are lethargic and some still just hovering near the surface or near the falls. I added an additional fountain to add more movement and oxygen in the water. Is there anything else I can do at this point?

I am so devastated. I can't believe I forgot to turn off the hose! 😭

Sorry to hear that. It happened to me too not too long ago where I left it running all day when I was away from work for 12 hours. I also lost one of the nicest fish in the pond

One thing I recommend is to estimate how much new water you added during that 6 hours, and double check the label and make sure you dose enough prime safe to sufficiently neutralize the chlorine. Also any additional movement of water will help to neutralize the chlorine faster. Other than that, I don't have any other comments. Hopefully other will provide you better advice.

good luck,

Aerate your water if you can.

Thank you. I have a chlorine test kit. It shows my chlorine is back to 0 after dosing it with prime. It was at 2ppm which is what my water's chlorine levels are 😔

I cannot even sleep waiting for morning to come and praying I don't wake up to all dead fish 😭

Thanks. I have two air stones going, high water fall, two jets raised upward to oxygenate the water, and added a water fountain pump for good measure. I just wish I could do more. The chlorine burns their gills so I wish there was some kind of medication I could give to alleviate that and help them breathe easier. But guess there's not. ��

I am sorry for your loses.

Do Gardena or maybe an equivalent supplier makes hose pipe garden fittings in your

part of the country.

They make an adjustable on off timer to run and switch off if you have remembered to

set the length of time for the hose to stop delivering the hosed water to switch off .

Nearly fail safe, just needs a human to adjust and to switch off.

Thank you. I'll look into it. I woke up with a second one dead. The others seem to be okay for the most part. They ate except for 2 that are still lingering around but more active.

Most of us have done it. More than once. Keep perfect water and watch ammonia ph and nitrites. You probably knocked back your biofilter. Have salt ready for nitrites

Oh good call out. Thanks, I will do that.

UPDATE:

So, out of my 37 koi I lost 2. The others are acting normal again and eating. Should I still be concerned? Could gill damage show up later? I am sad about the 2 I lost but definitely could have gone worse. ��

[fly4koi]

Relax, either way the boat had already sailed...

Keep an eye open for ammonia not that it's going to spike but it's not going too hurt to check it every other day for atleast a week and I would cut back on the feedings for atleast the same amount of time.

Have you purchased a hose timer yet? I use a circular mechanical hose timer that dials for different time increments. They are quite cheap and reliable but on my most valuable tank/pond, I use two timers in series (just in case).

Nowadays you can get wifi remote water taps with timer and flow meters. I have a linktap on a property that I only visit once a week for a pond takes 12 hours to water change. It is very accurate, reliable once when the flow meter portion stopped working, they sent me a complete replacement unit for no charge.

I found that using either my cell phone, or another timer, was not feel safe because I could wander off and leave them someplace where I didn’t notice they went off. More recently I’ve got a smart watch that I always said before I turn on the hose. When it buzzes on my wrist, I know to go out and figure out what it relates to and I have not missed turning off the hose since. But I also like the idea of a back up timer on the hose itself. Between the two, you would have a failsafe, or nearly failsafe situation. Sorry to hear about the losses. It’s never easy to lose a koi.

How are they doing?

[fly4koi]

Don't leave hoes overnight, kick them out.
(Sorry I just couldn't resist...)

Yeah, I have a wifi tap timer which shuts off itself in 1 hour so in case I forgot.
