Shane,

Trust me, they are not DIY drop checkers..I WISH I had such skill lol

I purchased them both on the Web. They are Boyu II type......

Yes, I use two and move them around the tank to help determine current, flow, c02 range.

Thinking of getting two more....

I agree. I think some DIY do add the white. Search around, I know someone has done it here.

 

I don't use a background. I take the DC out of the tank to compare it with the ph chart. The problem is if the light shining on the DC is not the same as the ph chart it's hard to compare. However, using a white background will make it easier to determine what shade of green you have in the DC.

 

Use non-transparent white suction cup (acts as DC backgroud) and place DC on the rear glass.
You can now easily distinguish color of DC's solution.

regards

 

I now use a Cal Aqua drop checker, with the reference color bulb. I find it pretty easy to match the colors if I add another drop of pH reagent to the reference bulb - I got Cal Aqua to acknowledge that this would work well. When I look at it now I am seeing both bulbs against the same background, so even if I can't see exactly what the color is, I can see if both bulbs are the same color.
