Stop Wasting Money On Dechlorination Solution – Koi Pond

Everyone knows that keeps any kind of fish, be it marine, freshwater, tropical, pond, or otherwise, know that chlorine in our tap water is a killer. Most in the hobby will spend inordinate sums of money of overly priced dechlorination solution, and nearly all the time, dose it incorrectly. 

First of the good news. After reading this article you will save a fortune in dechlorination solution as well as learn how to dose your pond correctly. As well as, finding a permanent solution that will remove the need for a solution all together.

What Is Dechlorination Solution?

Quite simply, it is Sodium Triosulphate. Which is a safe, easy to use, impossible to overdose chemical, cheap and widely used.  Crystallised Sodium Thiosulphate is very cheap, a kilo will probably cost you as much as a tiny bottle of normal dechlorination solution, but the kilo of Sodium Thiosulphate will last you 100 times longer if not more. Have you ever thought why they don’t put the ingredients on the label of these solutions? Simply because this is the only ingredient. There are many guides on how to use this chemical check out this one: How to Make Your Own Dechlorination Solution

You Are Dosing Wrong!

Many pond keepers are dosing dechlorination solution incorrectly. Mistakingly dosing for the water they are replacing, which is wrong. You should always dose for the entire volume of your pond, no matter how little water you are topping off with. Which makes the above method, even more of a reason to ditch the shop-bought varieties and make your own.

Need A Large Volume & Quicker Solution?

The above method works great and it’s always important to have that in your arsenal. Yet, there is another, more mechanical method, that simply means connecting a large chlorine filter and flow meter to your pond, when you want to make large water changes. For large water changes, I would recommend one of these: High Capacity Chlorine Filter and attach a flow meter to the end of it: Flow Meter – the above is exactly what I do and use and will save you money.

No More Water Changes – Koi Pond

Part of keeping Koi fish happy and healthy is of course water management. Making sure the water is as clean and safe as possible. There are various recommendations as to how often and how much water you should change each week. 10% per week, seems to be about the going average. For small ponds that may not be too much of a problem, for larger Koi ponds that can be somewhat of a headache. To that end, I use the following method:

Constant Water Change

Reverse Osmosis Filter

Using a three-stage reverse osmosis water filter, feeding into the pond at a constant rate, allows for a constant exchange of water. These can be hooked up pretty much anywhere and the small-diameter hose, can run very long lengths, in fact, it can be easily buried or hidden. These can be purchased easily online. 

Self Priming Siphon

Now, of course, having the pond constantly fill up with water means that it will overflow. To that end, it’s very easy to build a self-priming siphon, that will keep the water at a constant level. They are easy to build and plenty of video guides on YouTube will show you how.

By using the above method in my own raised wooden Koi pond, enables me a good degree of freedom. There are of course times when I do need a larger water change. I’ve written an article about dechlorination solution and how to save money on large water changes. Take a look at it here: how to make your own dechlorination solution for your Koi pond
