Re: [APD] uptake of nutrients, day vs night



what is your co2 at whats the ppm? I know that the photo period is opposite 
what it is during the day so the plants take up oxygen and release CO2 at 
night and day time the take up CO2 and release O2..

Have you thought about turning of the co2 at night. I know you said its a 
yeast based system so is it DIY or one of the commericial products if so 
which one.

Hello Folks:

I have been seening some of my plants pearling. A good sign.

What I want to know is what types of nutrients do the plants take up in 
darkness (night cycle) as opposed to the light (day cycle).

I noticed that sometimes if I add a dose of nutrients at night the tanks 
will look crystal clear in the morning. The plants look nicer as well. Some 
plants will also become lighter or paler in color, taking on a bluish tinge 
in the leaves, and continue healthy growth despite this. So I presumed that 
something goes on at night that does not occur in daylight. I do know that 
the plants will begin uptake of oxygen at night, thus competing with my fish 
for air. So I use a keralia nano to circulate the water at the surface to 
gently get more oxygen into the water at night and this works (the nano is 
on a timer). If not I find fish gasping at the top in the morining, due to 
all the plant growth. During the lighted period the plants take up CO2 and 
so my fish are fine, due the plants giving off oxygen into the water.

So now I would like to understand what nutrients I need to dose into the 
water column so I can dose the right chemical at the right time for optimal 
uptake. The idea is not to be feeding algea at the expense of plants. And 
that includes the slime.

Thanks, Diana
