JBL LIQUID TEST Vs SERA STRIP TEST

[simplepso]

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.

Reasons:

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.)

Seachem Excel would melt down my Valls, and egeria.

You might increase flow past the bottom of th passive diffuser or place a small hose feed into the reactor chamber to cause a slight mixing effect where the gas is, the DIY yeast method will add much more CO2, I'd opt for that as passive diffusion methods are tough to control and to add enough CO2.
The DIY CO2 mist internal reactor is dirt cheap to make and yeast and sugar.....well...that's fairly cheap..........and it's fun to watch. You can likely come up with something similar on your own for very few $$

The kh drop seen by sera test is strange
Look like your sera test is unreliable

Yast and sugar is better for co2 in my opinion :gw

Thank you Sir, Regret the delay in response.

I did build a DIY co2 and they are working just fine and great.
The only issue i face now, is that at night after the lights are turned off, the co2 rises to a level just below danger - which scares me.

Is there any option to control the flow or switch off the DIY co2 when not required.

Would appreciate a response.

Turn on an airstone or powerhead at night to off gas CO2
