Good morning Sps Polyp Extensions

[Sunreefer]

Hello all,

So trying to solve question of how to match the natural sunlight spectrum - since I get greater polyp extensions in the morning when I open my windows blinds and let natural sunlight in.

I run radions g4 and g5 blue with a reef brite actnics and blue leds strips (which blanket the tank).

I think Abe mentioned in one of his videos - 6500k spectrum, but I believe that is cool white instead of warm white. When I add more cool whites no difference. Something about the natural sunlight that the sps loves.

Outside of me opening my window blinds every morning and hoping to get max sunlight - any suggestions.

I measured par. Currently par around the tank ~400-500, but with the natural sunlight it jumps to 100-200 or more.

I think this more of a spectrum question than par. Thinking warm whites.

I can add a kessil 360x or get some led strip. I prefer not to go the t5 route, and have the need to change it out every 6 months. But if I must I will.

I find the most polyp extension happens a few hours after lights out. Have you ever checked extension with a flashlight?

My PE is good at night but its way better a couple hours after my lights come on and stays like that until the lights ramp down.

I only use LEDs (hydras) at an ab+ custom setting. No 6500k warm white

I don't think that lights are going to help you at all with PE. There are reasons that some might want to add in more natural wavelengths, but this is not one of them. Just my opinion.

If you do want to add T5s, you can use them for 2 years... maybe more if you just use them as a supplement or one year if you are super cautious. 6 months never was right and does not need to every get passed on.

My experience has always been high PH = full PE. I can tell when my top-off runs dry and no more kalk is being added by the reduced PE. As soon as I start dripping kalk the PE comes back to normal.

The corals in OP all look like Tenuis which should be one of the easiest acros to get fuzzy PE out of

My ph runs 8.22-8.33 day and night. Now when I open the windows and let the air it goes as high as 8.45.

Just puzzling to see pronounced pe when I see a difference with natural sunlight in the tank vs. not - all things being equal. Thought perhaps spectrum makes a difference - add more warm white (not cool white - which is a channel on the radions).

It could be not spectrum but more PAR, considering the natural sunlight did add more PAR into the tank. However, I would venture to guess having my lighting specs should be enough - I could be wrong.

I’ve seen tanks running heavy blues and others that run very white spectrum, both having good PE. So I don’t think it has a lot to do with the spectrum, IMO. I think it’s more of just how healthy/happy the coral is.

Another guess would be hotspots from your LEDs. If you’re running lower intensity in the morning when the sun is hitting the tank?
