Mmiller2001 Posted December 11, 2020 Share Posted December 11, 2020 What is high, medium and low light measured in PAR? Link to comment Share on other sites More sharing options...
Daniel Posted December 11, 2020 Share Posted December 11, 2020 I am not sure about high, medium and low but I just measured a 36" Stingray at 11" of water with a Seneye and this is what I got: 1 Link to comment Share on other sites More sharing options...
Daniel Posted December 11, 2020 Share Posted December 11, 2020 Roughly I have thought of low PAR being 40 - 50, Medium being 50 - 80, High being 80 and above. But that is just my own personal scale. Link to comment Share on other sites More sharing options...

FishyJames Posted December 12, 2020 Share Posted December 12, 2020 I ran across an old forum for planted tanks. Low light 10-30 par Medium light 30-80 par High light 80-120 par Link to comment Share on other sites More sharing options...

Ken Posted December 13, 2020 Share Posted December 13, 2020 This thread has just now given me an aha moment that I hope is the answer to my algae problems. I have been treating my 40 breeder like a low light tank, but based on the above it is not. I have the same lighting as @Daniel but fertilize like it is low light. Most of my other plants in that tank just survive. Maybe the only plant life that can thrive like that that is algae? Link to comment Share on other sites More sharing options...
