Suncorals too much light?

[Ninja120]

Can they have too much light? I have 250w hqi over a 24g and the suncoral sits at the bottom. Is it too much light that it might burn or kill the coral?

a 250w hqi over a 24 gallon might be too much light... I thought I had alot of light with 2 175's and 2 96watt PC's over a 55... My sun coral does fine on the bottom with no shade... but i think id shade yours...

does the light ever cause the skeleton to exposed by burning it?

Corals are burned by intense lighting when their zooxanthellae photosynthesize too much. This produces an excess of oxygen which is toxic to the coral. If a coral doesn't have any zooxanthellae (as is the case with non-photosynthetic corals like the sun coral), I don't see how it could get burned.

I used to have a black sun coral that did just fine directly under a 400 watt radium. So I would say they're unaffected by light levels.

my sun coral loves shade

Sun Corals do not need light... They will be fine under halides pc's whatever.. They get all their nutrition from food... The skeleton on mine is never exposed.

You need to make sure you are feeding every polyp every other day. If you are not doing this they will starve to death and their skeleton will expose...

If its not to bad now they will get flesh over that skeleton but id feed them every day for a while from here on out.

I have been trying to feed them photoplankton and food but their polylps wont open. I tried tank them out of the tank and putting them in a bucket with the main tank water and feeding them in there so they can get the food but still nothing.

Feed them Mysis shrimp... Dont take them out of the tank... they can not eat phytoplankton. Make a feeding hat and feed them

I have seen sus corals in nature (Maldives) exposed to the sun in crevides y a depth of 20 cm so, even if they do not need light if the water conditions of your take are prfect there should not be any problem. If the conditions are not correct some algae could appear in the base or in the exposed squeleton if there is any patch withiout tissue
