It seems that there is a problem in the way your CO2 is added... maybe a
bad reactor, or not enough CO2. There is another thing to look at... it's
the light... if you have enough light with enough CO2, you might see
little O2 bubbles gettng out from the plants... If you don't see that,
there someting not sufficient...
The Dupla permanent test is a good test, even if i find it's not the
ideal wau to measure the pH and CO2 in tha tank...
