Sunlight on my tank

[psycho]

Hello guy's

Since we moved to the new house I have noticed that my mushrooms are "bleached" and they don't look as good as they use to do. There is a few mushrooms on the side of the tank that gets no sunlight on them and they are green, green, where the other shrooms gets sunlight. Is it the sun that are "bleaching" them ?

Could well be, if they not used to the intensity of light. Is the light direct light.

Not direct sunlight, the tank stands outside on the "stoep" and the it is covered with fiberglass sheeting,

hi
i'am running an 250w mh with a luminarc and the last couple of weeks i've opened the blinds and let sunlight in on the tank and the corals have gone crazy more colour and more growth than before !

have you put the moved the m'rooms higher in the tank ?
it does sound light they are getting to much light i did have it when i first put the mh on ! all i did was shade them from the light with a bit of egg create for a week or so then moved it slowly and they are doing fine now !

Welcome jonothetigger - some nice advice there.

They are at the bottom of the tank, the same was as they use to be before the move,

I am busy making a shade net that I can hang infront of the tank during the day and then clip it off at night, I will post the photos of it as I go allong

do they look like they are melting ! i think thats about the best way to say it!
mine did and then they sort of lifted of the rock and floated away !

 

[psycho]

No they not melting, they are look bleached, very light in colour where they use to be a very dark green

sounds like light shock, they should recover, maybe target feed until they recover.

If it is light shock, how long will it be like that, it is now 5 months later

 

[Alan]

Wow after that amount of time i would say because of the light intensity they have expelled excess zoenthelia[sp] and this will be their colour. When a coral bleaches it normally goes snow white

 

[psycho]

I will take some photo's of them tomorrow, and post them. I will also post the "before" photos aswell
