Looking for glass type drop checker. I see them on ebay and some private internet sites. Ebays run $2-$10 and ADA is $38, big difference. Thanks for the info.

ADA drop checkers have the ADA symbol etched on. The Ebay versions, of course, don't, but the one I bought there, and most of the photos I see there look very good too. The acrylic ones don't look quite so elegant, but they work fine.

I purchased my glass checkers from Advance Aquarium Store and received it in less than a week. Communication via email was top notch as well.

Here are some pics of it:

Thanks for posting the link, I just bought one from there!

Hi mrkookm,

thanks for pics and link

I bought mine on ebay from aquaticmagic and it works well. Don't follow the instructions and use tank water though, but use 4 dKH water.
