bubbling? haiyo! when?

[ryan]

i'd like to know when all your plants start to bubble... like which part of the day... like how many hours does it take before your plants bubble... my tank only bubbles after 6... and the lights come on around 1... why? shouldn't they start earlier? anyway... please share...

quote from another thread by david

For a planted tank, a good level of KH should be between a range of 3 to 6, depending on your PH requirment when the water is CO2 rich.

KH 3 = 6.3 PH
KH 4 = 6.5 PH
KH 5 = 6.7 PH
KH 6 = 6.9 PH

Use baking soda or KH up powder from Aquamedic to raise your KH. Do not raise your KH by more than 2KH points within 24hrs(best at 1, at two you are pushing it but since you KH is at 1). dissolve the powder perhaps 1 to 2 teaspoon(flat not heap) and dissolve it into water. spread it around the tank....wait about an hour and test the KH level again....continue the process till the desired level is reached.
