Refugium

[stefday]

Hi,

I have put a few questions on about refugiums and I am very grateful for the advice given.

I have another couple of questions though,sorry.

I will have a Tunze overflow set up which should avoid problems from power failures but wondered what would happen if the return pump stopped working for any reason? I assume a flood but how can you avoid this?

How do you calculate what return pump specifications are required?

I just want a basic set up with live sand and caulerpa and possible some live rock. Has anybody got any designs for this?

Thanks again.

Stef.
