Tank is 3,5 months old.
Dry rock and sand, with live rock on sump from old LFS display.
30g total volume
Radion xr15 g6 + 2 gyre xf330ce
Stock: 2 clownfish + 1 pijama cardinal + 1 peppermint shrimp, 10 turbo snails and 2 hermit crabs
Parameters:
Sal 1,026
Ph 8
Alk 9
Ca 390
Mg 1400
AWC 2% daily using tropic marins classic salt.
Mechanical filtration: automatic filter roller. No skimmer
Routine: blow rock surface + sand 1x a week and coral snow
No dosing regiment yet since i only have a couple of zoas, 1 leptoseries, 1 favia and a duncan

I know this is probably just diatoms but since my tank has such a low stock (still waiting for my midas blenny to arrive) and I do AWC + filter roller, 2 weeks ago my nutrients bottomed out. I read 0/0 on nitrates and phosphates even tho i had reduced awc volume to 1% daily and almost doubled my feedings (pellets and frozen mysis) 2 weeks ago. Yesterday i read 0,2ppm no3 (dosed some and today results are 5ppm no3 and 0.00ppm po4)
Since i have lots of sponges and filters feeders on my live rock sump, i was not too worried about not reading nutrients. I even had some patches of GHA on my rock, but since i spot threated it last week, none have grown back and my rock is pretty clean. Thats when i started to doubt myself: im pretty sure I always had those brown patches on the sand, but i noticed it more clearly the last couple of days. Did I overfiltered my tank into a dino bloom?

There you go!
First tank and almost panicked with the possibility of dinos. Any tips on how should I proceed with my nutrient management? For now I deactivated my filter roller, hopping for a po4 reading soon
