Refugium Questions

Hello, after doing a bit of research on refugiums and discovering how benaficial one may be for my aquarium I've decided to make one.
I found a few links of people modifying aquaclear filters into them so im going to be taking that road and even managed to pick up a aquaclear 150. Now this is where my questions arise as to what exactly do I put into the refugium, Ive heard cheato? but what exactly is this and how is it benaficial? would the refugium need a sandbed? and how deep? is deeper better? or should it be shallow?
should the subtrate be fine or course?

Im sorry for all the questions , but this should serfice for now
and for your time...

I woyuld just add live rock and some chaeto. It is a macro algae that as it grows uses up nutrients from the water. The idea is for it to grow there and not have other algae grow in the tank and the growing cheato can suck up nitrates as nutrients.

With a refugium that small I would pass on the sand. I don't believe there is enough surface area to make it worth while.

I would agree that sand would make a better substrate. If you decide to change it out you can take 1/4 of the gravel/cc out every water change. You don't want to do it all at once.

I would replace the section you take out. Thats why you do it in sections.

Not sure about obliterated rock, LOL, I've always used either aragonite sand or pool filter sand when I need alot.

This is my tank and the sump/refugium I made out of a 75gal. I put snails and crabs in to help with the clean-up. Hope this helps you!
