Co2

[Grrriph]

Does any one have a simple solution for testing co2 levels and being accurate

I've ordered a test kit off of eBay. I don't believe theres a DIY test you can do.

I heard you can do calculations by knowing the ph and kh levels. But I don't know how to test kh. Soooo....

U buy a kh test kit then u mix it wit the solution

Add a bit of your water to some lime water if there is a lot of co2 the lime water would turn milky and a powder will form it was I'm my exam

The only accurate way to test is with a drop checker. The pH/kH test can be accurate, but it can also be skewed by buffers in the water. The drop checker uses a known reference solution and you judge the co2 concentration by the color of the solution. It'll cost about $15 to set up initially, but the solution only needs changed every few months, so replacing the solution is something you'll only need to do every couple years.

Yeah and those work good!!!
