Replacing pond liner - seeking advice
We've had our house for about six months now and are at last getting
around to replacing the leaky pond liner. With the pond, we inherited about 14 small-medium gold fish, along with one quite large koi carp. The pond itself will be about a 10ft x 8ft oval, with varying shelves and depths - the deepest being about 1.5m. I've read up on the subject and (plan in hand) am pretty comfortable with the actual physical design/construction process. What I have read conflicting information about is how long to leave the water to settle until putting the fish back in? The local pond centre suggests we keep the fish in a large barrell during the changeover and reuse as much of the old pond water as possible. So...we won't be entirely using tap water (about half-and- half), but some sources have said we should leave it a couple of days for the water to settle, and others have said upto six weeks! Can anyone give a bit of advice? Many thanks, Tim |

Using half the old pond water may speed up the process, but I'd tend to leave for at least two weeks if possible. -- ßôyþëtë London, UK |

The pond itself will be about a 10ft x 8ft oval, with varying shelves and depths - the deepest being about 1.5m. That koi can reach 3' long. You may want to consider finding it a home in a larger pond. I've read up on the subject and (plan in hand) am pretty comfortable with the actual physical design/construction process. What I have read conflicting information about is how long to leave the water to settle until putting the fish back in? I let it sit for a few hours with the pumps and an aerator running. That is if I use a dechlorinator (you may also have chloramines in your water to neutralize.) If not, then I wait at least 24 hours with everything running. I don't do this often as the ammonia builds rapidly in the holding tank/pool. The local pond centre suggests we keep the fish in a large barrell during the changeover and reuse as much of the old pond water as possible. NOOOOOOOOOOOO! That is not at all necessary. That water had dissolved solids you want to get rid of. Do keep some of the "seasoned" filter material to seed the new setup. So...we won't be entirely using tap water (about half-and- half), but some sources have said we should leave it a couple of days for the water to settle, and others have said upto six weeks! Everyone has an opinion. I've returned them almost immediately after adding a dechlorinator without any problems whatsoever. Can anyone give a bit of advice? If you keep them in a barrel or small pool for more than a few hours ammonia is going to be a serious problem. The safest thing would be to put them in a kiddy pool with 50% old water (to help acclimate them to the change) and add their old filter. Watch the ammonia anyway as this doesn't always work.

Tim The 2 most important things will be temperature and pH, not time, IMO. You can use some of the old water, if it is clear (no sludge or cloudiness). In fact, IMHO it will be less likely to go green, as you'll still have some of the balance from the use of the old water. Do have on hand, test kits for ammonia, pH & KH, plus a thermometer, Some ammonia detox and salt also should be purchased. Once pH & temp are quite close to same, you can move the fish. Then watch your water quality. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |

What filtration do you intend using? Using half the old pond water may speed
up the process, but I'd tend to leave for at least two weeks if possible. We've already got a pond pump and filter, which seems to do the job ok. |

Thanks for the info.
If I'm leaving the new water for upto two weeks to settle properly, will the fish be ok in a kids paddling pool (with current pond pump and filter running) for that length of time? Everyone has an opinion. I've returned them almost immediately after adding a dechlorinator without any problems whatsoever. What sort of thing is a "dechlorinator"? Is it some kind of filter or a chemical I'd add to the water? Either way...how much do they cost? |

It's toxic to fish and pond life. Here in the USA it's not expensive. -- RM.... Frugal ponding since 1995. rec.ponder since late 1996. My Pond & Aquarium Pages: http://tinyurl.com/9do58 Zone 6.

It is a product you add to the water to remove chlorine or chloramines put into the water at your local water source, unless you have a well of your own. It is usually available at the local fish store, but here is an example of one online. http://www.fritzpet.com/chlrem.html Regards, Hal |
