new 50gal RS 170, 2.5months in, mixed reef with a few fish.
I noticed brownish algae about 2wks ago that looked like diatoms. They went away after about 1.5wks. I used phosguard, and bottomed out my phos to zero. My tank was pristine for 3 days, and then brownish/green algae starting to grow again on rocks, sand and glass. I am not sure if my current algae is expected cyano, recurrent diatoms, or now dino's due to phos issue. The algae color looks the same, but now i notice algae 'strands'/'fronds' (not sure of the name) growing.
salinity 35ppm
nitrates 2-5
phos 0 ---- I removed the phosguard 12 days ago, although my phos continues to be zero despite multiple readings by hanna checker, and nyos testing kit;
alk 8.5
pH 8.2
was feeding pellets food 1x day with mysis 2x week for my 4 fish (clowns x2, cardinal, wrasse) before all this
i have 3 trochus, 3 nassarius, and 1 emerald crab
some coral frags - they all seem to be doing well
running skimmer, carbon, filter floss
RODI
not sure how to
1. diagnosis my problem
2. treat it
-is it brown cyano, and the next stage in my new tank
-is in dinos due to the phos? - I dont notice any bubbles, or a slime/stringy consistently
-is it recurrent diaotoms
I have started to feed now 2x day pellets, and mysis every day to try and increase the phos. I could dose phos?
pls help! Thank you !!
