...is too much, without adding CO2?
there is no formulaic answer. You must consider length of day,intensity, and range of lighting. you must also remember that plant density can have an adverse effect on oxygenation at night. At night plants give off CO2 and absorb oxygen just like fish....is too much, without adding CO2?
They do. They only become net oxygen producers when light levels reach "light compensation point".At night plants give off CO2 and absorb oxygen just like fish.
This makes sense, but it isn't actually true in practice away from a very limited range of circumstances.you must also remember that plant density can have an adverse effect on oxygenation at night.
Very informative. Thank you. Good to have you here, Darrel!...
The reasons for this are that in a planted tank:.....
As well as having a shorter photo-period, you can add floating plants if you have have very high light intensity.How much light...is too much, without adding CO2?
The "plants killed my fish" thread comes up quite frequently on other cichlid and catfish forums, and I understand why people come to this conclusion.Very informative. Thank you.
The tank (below) looks really good as an Apistogramma tank.So, I am thinking on upgrading the lights in my low tech Apisto tank. But not very convinced… I think probably not, not sure yet. ......One Sylvania Aquatar 18W (T8, 10000K).
Because floating, or emergent plants, aren't carbon limited, they will carry on growing in the "high light/low nutrients scenario". I maintain tanks with a lot of light, high plant biomass and low levels of algae without using added CO2 or Estimative Index etc.
If it is an electronic ballast (the light doesn't flicker when you turn it on) you only really need to replace the tube when it stops working.Otherwise and according to your belief I´ll just change the bulb as it probably is kind of wore out (i cant even recall when I last change it!).
