Aquarium DIY CO2 Drop Checker

Here is a step by step of making a DC. I found the plastic containers at Hobby Lobby, they are paint mixing cups with very tight fitting lids. The tubing is 1/2 in. thin wall from the pet store.

what is this for? Im very experienced in marine tanks but Im unsure of what this does?

[Ardell769]

It's to measure the amount CO2 dissolved in water for plants. It's only really useful if you're purposly injecting CO2 into your tank water.

The way this thing works, is by having water at a known kh without any ph buffers you can figure out how much co2 is dissolved in the water, by monitoring the ph of the water. so if you have a kh of 4 and a ph between 6.6 and 6.9 you know that you have a co2 between 32 and 16 ppm, in other words as long as the liquid is green your plants will be happy. I prefer to use a kh of 8 in my test solution. I hope this helps. OK VIDEO could be better.

Edit!! Two minutes to make a hole? I saw a video on building an airplane from scratch that didn't take this long.

Do you just put the same ammount of drops from the pH test kit?

I really could not understand what this was all about due to lack of narration or any text provided.

Are those containers ok for an aquarium? The plastic isn't bad? Have you have and problems?

[koxkokas]

how does it work? i do not understand how can it show the co2 level in the water.

I took a few ideas off of your video to make one myself. Until i get myself a smaller bottle.
