It's a great question. I want to take advantage of the T5 lighting I use so I keep the fixture lower to the water. I'm sure that has something to do with it. I would imagine if I had my lights 16" over the water it would have been much less of a problem.
I'd say 3 1/2". I've had her since Nov 2016 I think.
I shared my ideas... still waiting on yours!I have an idea - but I want yours before I speak out

I'm very curious to see what you have to say since you do have so much experience working with the red LED wavelengths.

I´ll get my new mitras lightbar 2 this week I hope - time to do experiment. However not 660 nm red - 630 nm instead.
This with polyp extension. Why do the corals extension their polyps sometime when it is lot of light (or certain type of lights). That they extend their polyps when it is food in the water - that´s one ting - but why do they do it more in certain light regimes? I have an idea - but I want yours before I speak out

Lasse, I really appreciate your willingness to share knowledge like this, even if it is just educated theories. I think you forget that 20 months ago I had never had an aquarium of any type. I follow people like you, Atoll, Paul B and Sallstrom because I have so much to learn from your experience.I was waiting for more to pick up the question
As I see it - the main problem for a coral when it have a high rate of photosynthesis is to get rid of surplus oxygen. The only way of doing this is by diffusion into the water. The rate of diffusion is
determined by the difference in concentration and the diffusion area. The difference of concentration can´t the coral not do so much about but to increase the diffusion area - more photosynthesis can take place. For corals with smal polyps - increasing of area means expanding of polyps.
Your case with lesser polypexpansion with whites and reds at 80 % can indicate that your PAR of the "high Photosynthesis wavelengths" has been to0 high and that photoinhibition taking place. I know that the white LEDs of the Mitras brand is very powerful and give a lot of red in the 630 -730 nm range. Better polyp expansion and better growth indicate better photosynthesis for me.
All of this is IMO

Nope. It's the cheapest 50" TV I could get. I could replace this thing 10 times compared to the outdoor TV's.
Thanks! The new settings do make taking pictures easier. I still do a little in the way of adjustment but the entire process is much easier.
Appreciate it! Taking pictures is fun when things are going well and the setup is easy.
