The future of co2?

[Jose]

Hi everyone. Have a look at this product.

https://www.kickstarter.com/projects/4612189/oco-the-worlds-first-co2-meter-for-aquariums

Anyone using it?
Does someone know more about how it works. Ifit actually worked it might be quite a breakthrough IMO.

considering he's issuing refunds on the kickstarter page, I'm going to say no

Sorry, the project has already failed apparently due to 'insurance problems'. Maybe someone else can tackle this one day.

Yeah, but maybe its DIYable? It seemed like an interesting thing.

There are some threads about it on the Barr Report. IIRC it's pretty much just a pH probe but encapsulated in a solution of something or other...

I recon the idea lies in using a co2 sensor this or this and a method to trap air between water surface and the sensor. Then read in values with a microcontroller and do some math (Henry's law) to evaluate co2 ppm that is escaping the water and entering the gap between water & sensor.
