In one word: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHH
This is real frustrating! At this point this is just a scratchpad.
Lightning in aquaria has several functions:
- for humans to see the fish and the plants.
- for plants (main function) (450nm and 480nm,650nm and 680nm)
- for algea
- probably the fish want to see something, but I found no specs about this.
Chlorophylls: Chlorophyll a .... 420nm and 660nm .... in all higher plants and algae Chlorophyll b .... 435nm and 643nm .... in all higher plants and green algae Chlorophyll c .... 445nm and 625nm .... in diatoms and brown algae Chlorophyll d .... 450nm and 690nm .... in red algae
Humans like so see yellow. Plants like blue and red as they already have so much green. The intensity can be measured in Lux (Lumens per square meters) or in Par (the full spectrum without the human curve/per ...)
