whats the bottle for? im new to corals and im learning a lot!
is it to stop it moving and to keep it in place?
Sun corals need to be feed lots but they have no zooxanthellae and cannot use light as a source of nutrition like other corals. so target feeding is a must even in a well established mature system. So to help target feeding I use a top of plastic drinks bottle lowered over the sun coral to stops food been eaten buy fish or been blown away by the power heads. This method seems to work well for me, you can see the polyps passing food to the gut and then extending again for second helpings
Hope this helps
Wow yeah that's a good price! Probably 1/2 to 1/4th of what you should have paid![]()
What a result

and boy have i ripped into the rock to try and get rid of the bubble algae once and for all
. I must have thrown 2 kilos of rock out as well. I have had the hole tank upside down {no rock has been unturned as they say
} plus i have moved all the corals into new positions in an attempt to make room for some new editions
}
, i think i have read somewhere that this is a common problem with xenia. I was just wondering what to do as it looks so awful now, should i take the rock out with it on and scubit in RO water to get rid of it. Then i can place new corals on the rock in its place. Or just leave it and see what happens. Just i don’t want it to die off and pollute the tank.
I am not sure what is going on here so any advice would be appreciated


Yep it was brutal i watched in horror as it ripped it out of its tube
and then pulled it under the live rock
