Hi,
After more than 10yrs without aquarium, I recently came back to the hobby. A great pleasure, however I’m dealing with some algae (not plague proportion yet, but I’d like to correct proactively if needed..)
I need help of more experienced reefers to assess what this is and how I should react...
2 shots of the algae (looks brown, cover almost everything, looks a bit “hair” type if left some time to grow)
My setup:
- reefer 250 with 2 hydra 26 (65G system)
- skimmer nyos quantum 120
- approx 40lbs of established live rock from another reefer (admittedly, some pieces looked much better than other who looked still very “white”) -> it was partially an “aquarium transfer” since I took rock, some water and a few living organisms
- 1.5 inch of Caribsea Hawaiian black sand
- few corals (softies, hammerhead frogspawn zoas)
The tank “transfer” happened approx 3 months ago, but virtually everything was new apart liverock and 50% water.
Parameters:
PH 7.9-8.3
Salinity 36ppm
NO3 undetectable
PO4 0.05
Ammonia undetectable
NO2 undetectable
KH 8.7
Calcium 460
Mg1420
Livestock:
Juvenile Purple Tang (doesn’t seem to like much that algae though)
Juvenile clownfish pAir
Juvenile McCoskers wrasse
Juvenile Yellow Wrasse
Juvenile Orchid Dottyback
2 juvenile cleaner shrimp
Cuc = mix of snails, approx 14 of them, one fighting conch
feeding:
Approx. 1 cube of frozen Mysis per day, in 2-3 times (or another frozen food)
