Just curious where can I get a good drop checker for my CO2 levels? Are all of them pretty much the same? Why do some people adjust so stuff for KH and so on?

Id like to ask, if i may, what IS a drop checker ?

A drop checker is basically a CO2 indicator that changes color depending on the levels of CO2 in your tank...pretty good way of keeping track of your CO2 without having to constanly check your kH and pH levels.

I'm selling AquaticMagic glass drop checkers. Check my FS thread in the Swap n Shop forum. I think BlackSunshine is selling DIY acrylic drop checkers, but I'm not sure if he's shipping to Canada.

dont' mean to thread jack as well, but I am wondering the same thing.

how do they work? do you put them in the water for good and just monitor them or do they work kind of like a chemical test kit?

Haven't actually gotten around to deploying one yet, but the concept is that you create a mixture with a known KH state (using distilled water and baking soda) so that when it turns green you have your 'desired' CO2 PPM state. As there are lots of things in a tank that can throw off the standard CO2/KH/ppm chart (which I've wrestled with for years), this small container creates a fixed state where you can measure the CO2.

Folks adjust the KH level so that the green state of the drop checker indicates different CO2 PPM levels. If I recall correctly, with a KH=3 green implies CO2=30 PPM. If KH=4, then green implies CO2=45 PPM.

Thems the basics as I understand them,

Yep. I sell some hand crafted acrylic ones. I guess you could call them DIY.
And I do ship to canada. there is a little extra postage tho.
Check my sig for a link to the thread.

Are they generally available at the LFS ?

 

[Blacksunshine]

not generally. maybe they might have the red seas one. If you're LFS is really really good and caters to planted tanks they might have some of the good quality glass ones. But those generally are much more expensive.
ADA's are crazy expensive.
Then you have ones like this

But those are still 30 bucks. +shipping.
