Well my dozen or more special of tubasstrea colonies some with over 100 heads and I've had for a very long time are open 24/7 , feeding them from a bottle is not a concern for me as I don't have animals that steal food.
Heres how suncorals work.
They need energy to open, they get back this energy from food, when they come out. And theres no food they use energy that's not replaced. If this happens to often they shut down.
When a suncoral doesn't come out it starts to provide energy the only way left, which by this time is to eat themselves from the inside out.
I'm not saying that a 2l bottle wont feed your corals I'm.saying there's am easier way to train without polluting your water quality.
Go to RC and read on the Tupperware method, unsing this method guarantees food several times a day and no wasted energy, after a week or two of doing this your suncprals will be open 24 hrs a day whether you feed or not.
I collect tubastrea and dendrophyllia have many species of both, fact is food is food, the idea is to feed the coral not the tank.
For me I use coral snow, fauna Marin and mysis, 2 out of 3 of these wont float nicely in a 2l bottle.
Not to mention not everyone has a sandbed....on RC we on the nps forumns decided while the 2l works its not as effective as the Tupperware method
, this method I
s designed to feed all day with as much pollution as possible and not pollute the tank.
Now what do you do when the suncoral doesn't eat or wont come out??
Also suncorals love flow it brings food to them.
