Acro Problem Help!!!

Is po4 and no3 always at zero? That's not a good thing ime.

Is there anything else to provide flow? Again, just my opinion but I don't think 2 mp40s Is enough flow for that sized tank....

What fish are in there? Any nippers? Checked for aefw and red bugs?

how are you maintaining ca and alk and mag?
what is your method of nutrient control?
your tank is relatively young..
