Can't seem to remember or find any device to monitor/measure CO2 concentration. I know what it looks like but not what it's called....can't locate on web. Device is glass bubble with curved stem of some sort. It traps CO2 which I presume I can then measure periodically. Any help would be, well rather helpful!

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.

Since, I received no written instructions on how this device works, I need some help. First, how long is the solution good for before it has to be replaced. Do you fill it up and leave it for a week, a month, or 15 minutes?

I assume I fill the little glass ball approximately half full with the kH Standard solution and then add drops of the B-Blue reagent?

Also, since my kit did not include the pH Brom.Blue stuff, can I just substitute 3 drops of my pH test solution that came with my master test kit? If so, how many drops do I use?

Sorry you were not satisfied with your order.
We do appreciate everybody's business, and I think 99.9% of most folks can agree to this. Sorry we did not include free items with your order.
If you would like us to send you pH reagent free of shipping charges and free product we will be happy to do so. If that's what would make you happy.

Your offer is appreciated, but no you don't need to ship them now. I really wasn't terribly upset about it. I always believe that if I am a tough customer, you'll be a better business. Accept it as constructive criticism. Still did not get an answer to two of the questions though.

How long can I leave it in the tank before I should "refresh" the solution?
Can I use my pH test kit or do I need to purchase the Brom.Blue reagent? Are they of the same concentration to give similar results?

Excellent questions!!! I'm betting that it won't change back once the "chemical" reaction has taken place, and that you (we) would have to periodically put new solution / reagent in the checker. If you changed the solution once a week, you'd go through that little bottle pretty soon. It would be nice to be wrong about this one.
