Green Star Polyps closing at the day time.

[Amiaki]

Hi all I'm new to a hobby, had my tank for about 5 month now and I'm totally in love with it. Right now I got 46 bow front with 20 gallon sump. I have 2 clowfish, and goby. 4 corals Torch, GSP, pulsing xenia and one that looks like a flower). But any who...

For some reason my GSP start closing at the day time about 1-2 hours after my day lights coming on (I have 2 OceanRivive T-247 LEDs (Blue at 70% and day light at 50%)). and it start doing it about a month ago. And it's still growing like crazy.

Any ideas why it might doing it? Before my torch wouldn't expend all the way for a couple of days and I found somewhere on the forum that it might getting too much light and I lowered my blues from 90 to 70 and daylight from 70 to 50. And now torch fully expending. But GSP still going back after 2 hours for day light and coming back about an hour after daylights are off and stay out all night.

Thanks

Well honestly it all looks good and since other things in your tank are doing well and the GSP is continuing to expand, I wouldn't worry too much.
When I changed from T5s to LEDs, my GSP went into hiding for six weeks but came back out stronger than ever. I'm not sure you can really hurt the buggers.
Perhaps someone else here has a different experience but personally I wouldn't wory

yep GSP are tough, but I have some under 2x165 led lights that prefer high and a few who will only get alone on the fringe of bright. You really want to PO them use a soft tooth brush to clean some algae off of them lol but you gotta do what you gotta do right

Two of those fixtures / 46 is quite a bit of light... I would go a little lower on both channels
It might look dim to you, but that's a lot of light. Beginner mistake with LEDs is to burn everything up..lol

I have two of the same lights on my 120 and I run them 60% blue and 25% white. Turn the lights down a little.

Picking out one tomorrow hope I don't have any issues with it.

Thanks for advice. I will turn it down to 60/25 too and we will see what happens. If I will turn it down and torch coral will need more light what will be the sign of it?

Torch and GSP on the same level (on the SB)

That's kind of the weird thing about this issue and why I didn't suggest lights:your GSP is angry but your other corals seem fine? Odd but give it a try and give things some time to adjust. It'll be interesting to see what results you get....

Another thing I forgot to mention is when I lowered my my LEDs from B90/D70 to B70/D40
my GSP was our for the whole day, but next day it went back in.

And what are the symptoms of a torch coral when they need more light?

Will go lower on day lights and post what happens.

little update after I turned down my day light by 10% so now my light B70/D30. My GSP stay out. Will post after couple days to know for sure if that was it was.

Thank for help.

I'd almost bet it will solve the problem. I have noticed this with corals getting extended for a short period during daylight cycle when water parameters are good.

 

[whosurcaddie]

Sounds good. Good that you made a smaller adjustment as well. Let us know.

i have a large colony of GSP and have found that the cleaner the water the worse they look. they do like dirtier water. just my 2 cents
