Again, the DC is absolutely useless for this type of investigation, however, as I mentioned, if you have a DC, then presumably you also have the DC reagent which is just a pH test kit. That satisfies option 2 above.

No, all of that is taken into account. It's just a rule of thumb.Doesn't the 1-2 unit pH drop for an ideal pH profile assume that all CO2 is degassed overnight?
Don't do that.I angled the spraybar upward last night to create more surface disturbance.
That's why.When I got up at 7:00 the pH was 6.90 rather than the 6.43 of the previous morning.
Good. Just observe and make injection adjustment if you continue to see melting. You can also supplement with liquid carbon (assuming you don't have any sensitive plants).I put the spraybar back to the normal position and by 17:30 when I got home, the pH was the same as the equivalent time yesterday: 5.6.
Maybe there is a smidgen of hope that I have got sufficient CO2 and this meltfest may be averted?!
So we can use hobby-grade test kits to measure KH?Use your KH test kit to verify the KH.
I guess I should watch this film. Will it help me grow healthier aquatic plants?That is what they teach you in The Matrix to turn Human Beings into a Cash Cows.
Hi Sacha,The Salifert one is very good.
No. KH test kits do not actually measure KH. They measure alkalinity. For the purpose of this exercise however, the number that we get gives us an idea of what the pH drop should be (low, medium, high).So we can use hobby-grade test kits to measure KH?
Dream on Copper Top.....mooo....The Salifert one is very good.
Mmmm. Reminds me of my school days!Have you paid attention to the difficulties experienced by the OP in this thread...
Hi Sacha,Condescending and patronising comments aside,
The Salifert test is a titration test kit, meaning it provides good resolution to an accuracy of 0.2.
As Clive mentioned, it measures alkalinity and then uses an algorithm to arrive at a "KH". The KH reading isnt 100% reliable. But it is the very best you can hope for from a hobby- grade test kit.
