Stringy brown diatoms. How to remove silicates without removing po4

[BuddyBonButt]

Amino acids are a fine way to add nitrogen.

Oh so nëonitro removes the necessity? I've been doing blackouts, nëophos, nëonitro, microbacter⁷ and now silica to keep dinos away. And they keep pushing back with me having MUCH lowered lights, copapods, 15 nitrate, .1 phosphate and constantly manually removing dinos from socks, leaving skimmer off, or leaving lights off completely... idk what else I can do
