Which aquatic plants absorb nitrate most?

[properfool]

i think very hard for anything to grow under 4hrs of pl light/day. Anything that takes up nitrate well generally grows pretty fast. Grows fast often need energy which will need light.

The low tech tank approach by D walstad advocates floating plants.

minimum Photoperiod for effective photosynthesis in plants is a minimum 5-6 hrs. less than that you won't get much results

Won't they drop leaves? Will be messy if they do... That's why i hated stem plants.. Not enough lights they drop leaves and the whole tank will have lots of floating dead leaves...

I dont experience dropping of leaves for this plant. There are quite a few that does. I like stem plants, so no choice. Every few days use tweezers and pick them up.

hey guys do you all use a chiller for the planted tanks ?

i went to a shop and the guy told me that if the water too warm , the plants will produce ammonia or nitrates ? is it true ??!?!

Which means the plant died and rotted? 26-29 C will be good enough. Which can be achieved by usage of fan.


Finally found the name of the easiest stem plant I grew - Water Wisteria.

Think i really have to adjust my lightings to 5hrs a day? Hopes it helps...

my lights are 8 hours daily, but i think it depends also on the intensity and the other conditions.
i am having algae on the glass now, which i thought would not be with just 8 hours.
but i am doing gujing and downoi, both are really a handful and dead worried they will melt on me again.
