PAR Measurement!
These measurements are my lights driven to 100% Blue, 75% White, 100% Green, 100% Red.
The two light bars are slightly offset here, leaving the front right corner falling off in intensity rather quickly.
I'm still actually slowly increasing brightness while trying to control algae, so my current "daylight" setting is 50% blue, 10% white, 0% red, 0% green, until the rest of my CUC gets out of observation.
Diatom bloom in the fuge now appears to be rapidly receding, below is yesterday, a day or so after the bloom peaked:
Yes, that's diatoms... I've been running blue and violet only to keep green algae down, which is why it looks red even with my makeshift yellow filter. Here it is under white-only:
The pinkish areas were all solid brown a few days ago... at this rate I expect it gone reasonably soon.
