Multiple photo periods

[Proteus]

Does anyone run multiple photo periods of a shorter time on there sps reefs

Eg. 2 4 hour periods

I did some reading on this and people claimed faster growth but no pics to show

Like 4hrs on 6hrs off 4 on?

[Proteus]

Exactly

The theory is that the corals ability to process light into food after certin amount of peak light hours requiring it to shut down. So after a rest it can process again

Apparently by increasing cycles you would double growth rate. Basically two years of growth in one

[subman]

Interesting theory and does make some sense. I may have to try that next time I go on holidays

[Proteus]

I am thinking of trying it. Just want to know if other people do

[Relect]

Check out gaslamp method. Though its done for plants people report crazy growth while using less light. Sometimes less is more.

i've always wondered about this.... 6 hours on 6 hours off, repeat..

If you do go ahead with this Titus please heavily document the growth - I would be very interested in teh results.

Does anyone know about light saturation at different kelvin

[Proteus]

i made a program for the radion. its 6 on 6 off with half hour ramp up and down for each period.giving it 5 hours peak. its 18k @ 90% which is the intensity now. i am going to take some notes and pics and implement this program tonight. i may adjust length of peak intenstiy as it goes on

on a side not i just read without any proof that sps grow there skeletons at night. can anyone comment or verify this

I read something a long time ago about supersaturation and excess zooxanthallae with too much light. It prompted me to reduce my photoperiod to between 5 and 7 hours. I get much better colors than I used to. I currently run 7 with LED, but my MH were on for 6.

No idea about growing at night. It could be, I know we build and repair tissue when we sleep :)

I think there was a thread on rc that was showing the best growth on their frag tanks with 4 hours on, 4 hours off

Ok I uploaded program to lights. I changed it to 4 hour max intensity but retained the 6 on 6 off. Just a longer ramp

I suck at pics with I phone but here's a couple for reference

This is some of the pieces I want to see better colors. Most others are great color. Just a reference
Orange grove is brown with green corilites
Blue acro is brown with light blue color returning
Red planet is green
Shades of fall is white with reds coming into base
Red convexa is orange with red tips
Garf is pale blue tips brown polyp a
Fuego is green with violet tips

Dang I have my halides on for 10 hours mainly for my viewing pleasure I may have to rethink this

[Proteus]

I found a thread on rc. It did talk about photosaturation and that test have been done and in said test photosynthesis continoued for 20 hours during intense light.
It did state that the split cycle will drive fish bat sh*t crazy. So we will see how that turns out
According to the thread on rc 75% of calcification is don during daylight hours

well its been ten days since i started this.

so far its been very good, a few of the corals are showing new growth. my purple poison shortcakes growth has taken off, i really connot believe how much its grown

as for color nothing yet for considerable change

fish dont seem to mind. my pipe fish did hide for a day or two but it along with the assessor and shrimp are fine

one thing i do like is first light schedule is on when i get up for work so i get a quick peak before im out the door
