4 Dkh Solution For Drop Checker

[Colts]

Hi,

I've just ordered a chameleon drop checker from ebay which comes with a Co2 test regeant. I'm assuming this is nothing more than the pH test regeant as it's such a small bottle. Does anybody know where I can get some 4 dKH solution from in the UK?

I know aqua essentials sell it but at £13.24 delivered I was hoping there would be a cheaper option available.

that bottle will last you years, you use about 2ml tops and changing the solution every week means it lasts 250 weeks (approx £0.05 per week)

The only other solution is to make your own.

Add 6 grams of bicarbonate of soda (baking soda) to one liter of distilled water. This gives you one liter of water with a KH of 200 dKH. Then take 10 ml of that water and mix with 490 ml of distilled water (a dilution of 1 in 50) and you get 500 ml of 4 dKH water.

This makes 5000ml of 4dk solution (providing you use all 1000ml of 200dkh water) so you could sell some on if you wanted.

Make sure you have a set of scales (.01 degree of accuracy) and test the solution after. Exact measurments is important.

do you mean by scales to measure the KH?

That's what's putting me off buying it. I believe in buying in bulk to save money but this seems way over the top.

Are there any guides available for making a DIY solution and do you require any special equipment?

You need a set of scales to measure the 6g of bicarbonate of soda.
You need a kh test kit to test the solution is the correct kh
