Reef under Siege - Waterbox AIO 50.3

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.

Got new inverts today from the Reef Cleaners order.

Still acclimating, unfortunately neither of the pom pom crabs made it. SIP, little guys - I'm sorry.

Shame, I was really looking forward to having them, and I REALLY hate losing livestock. I have to admit that kinda ruined my day.

Forgot to measure PAR in the 'fuge... HOLY MOLY!

That little NooPsyche K7 Mini driven at 30% each on the white, blue and violet channels, is hitting 230 PAR at the bottom center of the tank.

At 100% on all three channels, it's straight up 500 PAR!!

Unfortunately there seems to be some non-linear scaling in power output on the blue channel between the 19% and 20% setting, with jump of about 65 PAR when measured at the same spot (near dead-center of the tank). In order to keep my gracillaria happy without moving it from where I want it to live, I had decrease blue to 19% and increase white and violet to make up the difference and get it near the 150 - 200 PAR I want in that spot.
