 Cool Nights Can Adversely Affect Your Filter

This time of year can see nighttime air temperatures dipping into the low 50s. Although a welcome break from the summer heat, these cold nights can be temporarily detrimental to your pond's biological filters. The "good" nitrifying bacteria that remove toxic Ammonia and Nitrite from the system can be killed off or made dormant by these sudden drops in temperature. With fewer bacteria to process these chemicals, Ammonia and Nitrite can quickly increase to toxic levels.
A number of steps should be taken to prevent fish loss due to Ammonia and Nitrite spikes caused by cold nighttime temps.
  1. Test you water for Ammonia and Nitrite more frequently, and definitely after cold nights. Remember, don't feed before testing it will skew your results.
  2. Have Ammonia binder and salt on hand to protect your fish from Ammonia and Nitrite spikes. Don't wait until there's an emergency to pick up these essentials. Ammonia binder can be bought online here or at the farm.
  3.  Hold off feeding you fish until midday or so, so that the water is warm enough for the bacteria to process ammonia effectively. Remember, food in the pond becomes ammonia whether it's eaten or not. When the water is cold in the morning, even if the bacteria is alive, it can be sluggish and won't process the ammonia as easily.
  4. Review the Science of Water Article (click here to go the article) so you can understand what's happening and can act quickly if (or rather WHEN) something goes wrong.
As always, be diligent and proactive to keep your fish healthy for years to come.

The New HKF

All winter long Chris and I have been working on this new website. Finally we are able to launch it in time for the upcoming 2017 season. It is not 100% complete but close to it! Every single article has been updated, and this includes new information added to each. As well, we have added tons of photos and videos to make learning about Koi a little more enjoyable. Not to mention I needed something to break up my long winded articles LOL. We added more symptoms with photos and videos to better help you diagnose any issues you may have with your fish. No one has a more comprehensive website for Koi!

Also new this season, in the near future we will be holding online auctions for Koi on the website! This feature will be available sometime after we open for the season and get the fish from the ponds to auction. These will primarily be larger fish or packages of multiple smaller fish. With an auction format you will have a much better chance of getting some great fish below retail!

We are Expanding!

In addition to the new website, the other big news this season is that we are growing the business and expanding our inventory! No, not more fish...we already have more of those than anyone Duh! We will have a very nice selection of pond plants again, including lilies and all the most popular varieties of water plants and marginals. Even bigger news is we will be carrying outdoor and pond associated statuary, chimaneas, bird feeders and much more as the season progresses! We also increased our pond equipment line as well!

More Fish Then EVER!

The retail tanks will be overflowing with thousands of great fish soon! We have more fish than ever, and many new varieties that you have not seen in a while. As usual, you will be pleasantly overwhelmed at our selection. No other place comes close to our selection of Koi and Butterfly Koi. We truly do have more fish in more varieties then you've ever seen!

It's worth the drive!

So, if you are looking for Koi or Butterfly Koi, you need to make the trip to the farm. We can say with confidence that you will not find a better selection ANYWHERE! We promise you will be delightfully overwhelmed at the huge selection and the great pricing! If you are within a day's drive of the farm, we would highly recommend you make the trip. No one has ever been disappointed! Many folks drive as long as eight hours or more to come here, and some even fly in to be able to personally pick their own fish. If for some reason you can't make the trip, you can always buy one of our package deals online, and we personally will pick an awesome variety of fish for you. You should also keep in mind, however, that we are also very close to Amish country in Lancaster, as well as historic Gettysburg. So you can even make it part of a long weekend or vacation and pick them yourself.
