Not real happy with Green Leaf Aquarium folks. Purchase was received with one glass dropper and one bottle of the kH Standard, but no instructions, no chart, and no pH reagent. Apparently, after I received my order, their website changed to include all the items that I did not receive for $5.00 more. I can accept that they changed their site to now include the pH reagent solution (Brom.Blue stuff), but it's pretty cheap not to include the written instructions or the chart. Just poor customer service. I want to do business with people that appreciate my business and do the extra things to show me that. The little things that show that they want my future business. These folks failed in that reguard. I'm sure there are many who have had positive experiences, but I draw a negative on this one.

I have found that Orlando goes "above and beyond" with customer service. Did you contact him directly before you posted here? I can see you might be put out if he refused to correct the problem. No one is 100% perfect - mistakes are sometimes made.

From others, I have gotten 2 different drop checkers with "unreliable" instructions. Most say to use the water from your aquarium which is incorrect. I never had any drop checker come with the 4dkg water and I have purchased 4 of them. Seems to me that Green leaf offers full service. I do see the instructions on the web site. Maybe they weren't there when you got yours. (I do think they should be included with the drop checker.)

ok, so your color does change...can someone that has a single bulb DC chime in on how their color changes, if at all?
from what i understand, co2 will leave the water pretty quick of you stop the flow. if that is the case then the DC should turn dark blue just like it was originally when first added to the bulb. if the DC doesnt change back to blue then it doesnt really work like i expected and im going to be disappointed.

can anyone explain how it works?

i assume the co2 enters the DC and reacts with the fluid to change its color. what happens to the co2 gas at that time? does it break down into something else? what is the by product? how is it possible for the co2 or the by product to escape the DC? i dont see how it can. if it doesnt escape then how can the liquid change back to blue?

also, the directions dont say where to place the DC in your tank but i did read that you should place it on the opposite side of the tank from the diffuser. that is fine, but how far below the surface of the water should the DC be placed?

thanks.

From what I understand CO2 moves more quickly from air to water than O2. So if you have less CO2 in the water than the air it will go back into the water and be dissipated, replaced by the O2 that is now more prevalent in the water since the CO2 has lessened. Hence the drop checker reverts back to the blue color. The little air bubble reverts as well. When the CO2 rises it traps in the air bubble and the water and changes the solutions color back to green to yellow.

Guess I was a little late in posting.... LOL They were much more succinct anyway!
