Hi forum
I have been trying to measure my kh of my tank water for the last few weeks,I have 3 kh test kits that I have been measuring the tank water with, I no all test kits are not going to be accurate and will give different results.
So I have tested all 3 test kits to a 4dkh solution that i use for my drop checker that I purchased, as a reference point thay were all very close in the results,then I measured them all on my tank water that is high tech with co2 in it and all 3 of them had very close results.
Then I took a cup of my tank water and let' it degass of co2 on the side for 3 days just to make sure it was fully degassed of co2 and tested with the 3 test kits thinking it would be the same results as in the tank.
But there was a really big difference, where as it's was taking 3 drops of test kit solution to turn from blue to yellow it was taking the degassed tank water 7 drops of test kit solution to turn from blue to yellow,these results happened on all three test kits
Question
Can anybody tell me why this is happening?
What results should I take as my kh, the degassed tank water or water in tank ?
Has anybody come across these results them selves ?
