Not hugely scientific this test but I am just testing to see if there is a different reaction time between these 2 drop checkers.
Reason being that the 'Teardrop' style uses a tubelike opening for the gas to enter it's chamber which is approx 5mm wide whereas the Chameleon uses the wide approx 20mm 'mouth'.
I am expecting the Chameleon to be the clear winner.
Firstly here is the equipment: 'Teardrop' drop checker, 'Chameleon' drop checker, 4dKH solution, AP Ph test drops, syringe. The DCs have still got the previous mixes in them here.
Just to go through my changeover routine firstly I use the syringe to remove the old mix, then I take some 4dKH water and syringe it into the DC, slosh it about and let it settle. This will dilute any of the old mix left in the DC and also clean out the syringe of any contaminants. you can see here a slight remnant of blue in each DC after putting in the fresh 4dKH water:
Next I remove this water which I used to clean the inside of the DC and add some more fresh 4dKH water. I am using 1ml in each DC so that they are working with the same amounts. Will give the 'teardrop' a fighting chance:
Then I add 2 drops of the AP Ph test:
And finally put them back into the tank. They are side by side on the opposite side of the tank to the CO2 output:
I have turned both lights on for this photo and will do so for each photo I take so that the lighting doesn't affect the colouring. I will of course turn the lights back off to keep within my normal photoperiod settings.
Time of this first picture is 11am. CO2 will turn on at 3pm when I will take my next picture. This next picture should show by its colouring what is already in the tank pre-CO2 injection. After 3pm I will try and update every hour just so we can see the change in it's stages remembering of course that each photo will be showing what the concentration was a couple of hours previous to when the picture is taken.
Not a hugely scientific test but each DC has the same amount in it so should show that the wider 'exchange' area gives a faster response time.
I do have to add that as you can see in the pictures the Chameleon is much easier to gauge a colour from. This is not because the teardrop is further away or in the shade. It is just much easier to see the colour with the Chameleon.
Starting Ph of tank water is 7.2 and tap water is 7.4, (according to the same AP test kit used in the DC)
temperature is 25ºC
