I have had this algae outbreak for a few weeks now. I’m not new to the hobby as I have 10 years in it but Iv never had anything close to this. Honestly I’m not even sure what type of algae this is. It’s so thin and almost bacterial like cyno but it’s not the right color and Iv seen plenty of cyno. Chemiclean had zero impact.
the algae is just overtaking everything. Iv scrubbed the rocks clean and did a 20% water change twice in the last two weeks. Two days later it looks like this again.
took a fresh set of parameters for this post. All taken with Red Sea tests or Hanna test. RoDI water is used that shows 0 TDS, using Red Sea for my salt.
Tank 93g - ~110g total volume
NH3-4 - O
No2 - O
No3 - 2.3ppm
Mg - 1400
Alk - 9.4
Ca - 442
Po4 - .02
Ph - 8.09
Temp - 78
Tank was started 10/15/2021
Nothing but dry rock was used. No live rock has been in the tank. Sand is ocean direct sand that was bought new.
lighting - eco tech xr30 g4 with two reef bright strips. Set at 40% on soft/lps setting and 6.5 hour light cycle.
