I’ve been dealing with a stubborn/persistent but minor (so far) bit of brown algae (hopefully algae) for the past 3 weeks or so. I don’t have a microscope, and I’m hoping someone here might be able to visually ID?
Tank is 3.5 months old and I had a small diatom outbreak 2 weeks in. Using natural sea water collected in Winthrop (0tds RODI for top offs). The “algae” tends to diminish a little overnight and return midday (making me want to rule diatoms out). It’s been like this for about 3 weeks and sticks to the substrate only. Nothing on the rocks.
Tank is a EVO 13.5 running an AI Prime 16HD (Saxby settings). Mixed reef (softies, LPS, and few montis), 4 Astrea Snails, 3 blue leg hermits, 1 nassarius, 1 skunk cleaner, a tailspot blenny, and a small DaVinci clown.
Params:
Ca-420
Mg-1285
Alk-7
No3-<1
Po4- .02 ppm or less
salinity- 1.025
Temp- 78
I’m doing biweekly water changes of 30% and siphoning each time. I’m also manually removing it a few times per week. It pulls up relatively easily with my tongs. Sort of staying the course until I can figure it out.
Also, running filter floss, Chemipure Blue (2x nano packets) and bio media in chamber 1.
I’ve had 3 reefs and I don’t recall having this before. I’ve had plenty of diatoms, hair, bubble, and other algae before, but this one is different.
trying to figure out the best course of action. Thoughts on whether we’re looking at Dino’s, diatoms, cyano, something else? Thanks!
