Who runs surge devices.

I was just wondering who ran surges on their tanks & if you have any pics. 
I was sitting in my thinking chair the other night & had an idea.
I was thinking of adding a surge & also using it to slowly feed the tank throughout the day instead of 1 or 2 big feedings.  I thought about making some home made food & then mix it with some ro water & freeze it in a freezer box.  In the morning drop a big food ice cube into the surge.  If it melts too fast I could fasten it towards the top so water only hit the cube a few minutes each hour.
Thoughts?

 

It looks good cept I will have lights over the whole tank & no room for something like that. I will have to have it to the side of the tank & run it in with a pipe.

 

I realize how to make one.

I was wondering if people saw better coral health with them. That and add in a slow feeder for better coral/fish health is my main goal. Unfortunatly on the reed fish & coral eat all day long, just not in one 15 minute period.

I thought about using Bornemans plan to reduce air bubbles but dont like the idea of a pipe sticking down into the water. I am going to see if I can hide one on the side of the tank. I thought about putting a bulk head in the side about 5 inches from the top.

That & I will have to make sure I am not going to flood my sump when it flushes.

I did a cut & paste on pics seemed to work for me. I have a hell of a time adding pics since I am not camera/computer gifted.
