CO2 at ~30PPM With No CO2 Injection?

I ran my CO2 for a few hours on Tuesday when I first installed it. I got up to 30PPM CO2 within a few hours, then it was almost bed time, so I shut it off.

Yesterday morning I was still at about 30PPM, so I didn't run any CO2 while I was at work for the day, but left the light on.

Ran CO2 for about 30 mins last night, then turned it and the light off (light off a little after CO2).

Checked this morning and I was at about 20-30PPM...

Do I just not have enough plants to use that much CO2?

I'm really new to high tech and I don't understand what's going on.

How much water movement do you have in this tank?

Other sources of CO2: Decomposing waste, fallen leaves, fish food...

How are you measuring the CO2?

There isn't much movement, but there is some. It's a Betta tank so I can't have too much.

The plants are new, so no fallen leaves laying around, and by betta eats all of his food.

CO2 "measured" with a Fluval CO2 indicator and the pH/KH chart.

ETA - I baffle the pump output at night so there is pretty much no flow. During the day the baffle is off and its enough to agitate the surface a bit, and push a piece of food around the tank. (Fluval Spec V/5Gal)

Are you using 4 dkH reference solution in the CO2 drop checker? If not, it will provide erroneous readings.

I'm a noob! I just used what was in the Fluval drop checker kit that I ordered.
