Data

  • Age: ~ 2 1/2 months (looking at my receipts, I started this around 12/15/21)
  • Size: Fluval Evo 13.5, ~10lb live sand and ~10lb of dry rock in the display (and another ~2lb of crushed dry rock in the middle chamber)
  • Ammonia: 0 ppm
  • Nitrite: 0 ppm
  • Nitrate: 9.3 ppm (30-day avg is 6-10ppm)
  • Phosphate: 0.12ppm (30-day avg is 0.1 ppm)
  • Calcium: 482ppm (30-day average is between 470-490)
  • Alkalinity: 11.4 dkh (30-day average is between 11.4-12 dkh)
Coral is continuing to thrive, but I took a quick snapshot to check and see what I have going on here. What I am doing is...

  • 3ml All for Reef spread across 12 doses per day
  • Food: Red Sea AB+ for coral, shrimp for clownfish daily, around 10a (when the lights turn on)
  • Microbatter Clean (one capful) the last two weeks (same time when I do feeding)
Here is the pic. I am pretty sure this is part of the ugly phase, but is it diatom, brown algae or dino? No air bubbles and the nutrients aren't high enough for me to think dino but it's something to throw out there. At this point I am just curious and looking to expand my knowledge :)

(Note the photo was taken about 20 mins after feeding).

Thanks for the help!

Appear to be diatoms
Some causes are:
Type of water used
Expired Di resin
Newer sand
Newly added rock
Inorganics

nothing of concern except it’s appearance
You can always siphon lightly if you don’t like the sight or it
Reducing white light intensity and adding snails such as:
Astrea
Cerith
Nerite
Trochus

Will help reduce and control it
