HYDRO UV clarifier cal, mag, iron

[Bartholomew]

Hi,

Does anyone have any experience with UV clarifiers? I know that UV "sucks out" some nutrients from feed water. How much should I add back?
Should I run the UV clarifier 24 hours a day or less?

Thanks!

Only when too lazy to clean my fish tank...these serve no use when growing weed (IMO)

UV light can be used in volume when finishing off the trics very close to harvest day but then rains then come

ideal in fact but in general a danger to health

Are you talking about uv grow lights?

I’m taking about uv water sterilizer/clarifier.

Uv clarifiers disinfect hydroponic water. Great way to prevent algae and other infections.
