@sjw @fluffy Is that a euphemism or meme or do people actually use rice to filter? I read that uv will deplete bioavailability of nutrients in the water (breaks down the salts and they reform), so consider a "quarantine tank" setup possibly. >Multiple tanks and T-valce.

Sort of like dialysis. Time nutrients for when you switch tanks.
