JBL Water Test Set, For freshwater aquariums, ProAquaTest CO2-pH Permanent

Seems to work fine and detect my CO2 levels.

Works well. Good quality test

Ok but expensive.

The liquid is really good, but the checker not at all, the hole is too small, the colour change with the same liquid is slower and as it have a cap, you can't see the light through making the reading a bit more difficult. But in the overall is a very good product

Excellent, works as it should, well packaged and arrived in good time.

Not much to say about best co2 indicator. Worth every cent.

Doesn't work. After following the instructions, I placed the required drops into the test capsule and a month later of thinking the co2 levels are being monitored, I now learn that this solution requires an additional 4 dkh standard solution to work - otherwise it will permanently measure 'low co2' even when the tank is so saturated the fish are gasping for air.

- Looks good - Works well but slow to change colour - Easily leaks, level of solution drops over time and recently disappears in days - Glass drop checkers more reliable and less likely to leak

Muy buen medidor de CO2, merece la pena pero algo caro

Correspond à la commande et facile à utiliser

Génial, conforme à mes attentes.👍👍👍👍👍

Perfekt !!

ok
