Setting up a frag tank questions.

 

In this picture you can see where the frag tank will be placed in relation to my main tank. It is a 20 long.

 

 

This is a view behind the main tank and looking at the sump.

 

This next one shows the sump with an extra return. ( I have some cleaning to do as I have just moved things around) The reason I have an external sump is because this tank is in a school and I allow students to learn about the setup...see the good and the bad I guess.

 

 

What I was thinking about doing is to drill the return on the left side of the 20L end as seen in pic #2. Running a divider down the middle with about 4"~6" open on the far end. This would allow for more water movement and place a powerhead pointing at the return to the sump. The flow would be in a "U" shape. This would allow for me to put LPS under the return from the sump and SPS before the return to the sump.

 

Next question is should I go bare bottom or sand? I am planning on using egg create rack.

 

Thanks,

If you are not providing ahigh current flow, I would use a shallow sand bed in the 20L just to provide the coral with some live food.  If you want high current, I would go with bare bottom...
