Hi, just a comparison between both the subject mentioned tests.
After the co2 tabs where added, as per the sera strip test there was an increase in the co2 and decrease in PH which is what we expect. But unfortunately on the JBL liquid test - no changes were reflected.
1) Actually Sera Co2 tabs did nothing when added which reflects on the JBL liquid test
2) The JBL Liquid Test might have been expired as i have this kit with me since last August, 2011.
3) Sera Strip test is trustable- as it gives me what i had expected - increase in co2 and decrease in PH while adding the tabs.
Please advise what seems to you...
Below is the small chamber inside the aquarium where the co2 tablets were added and will be added depending on the requirements.
(y? all this was done because i had a very low co2 of always below 10 mg/l. And, currently i cannot afford and rather not intrested on a full co2 setup.)
