Could I get some advice guys

Been around the forums again and the refugeum keeps coming up for improved aquarium corals health.
What benefit is it to an aquarium guys, what do they help with?
I just want to keep up with any and all ways to keep getting awesome out comes for my nano.
Thanks for any advice.

Good topic,this is something i'm wanting to get into as well and there is no real way to just get this.
The talk on the forums is all over the place,do it this way,do it that way,look at mine and i have,man am i confused
Easy info to get your head around,please

It’s like most things that can't be just purchased, what way will it work best, what size or shape do you go with.it can do your head in!
A mate has one on his, he had to make and plumb his own.
He got an acrylic box, like a small tank for the back of his tank, the pipes that come out of it sit just above the edge of the tank so the water that gets pumped in naturally flows back into the tank.
He has all kinds of macro algae over a course substrate and I am sure I have seen sponge in there also.
He said it helps take phosphates and nitrates out of the water and feeds the tank some plankton that he has growing in the refugium.
He’s had it going for nearly a year and there have been no probs.

They are awsome for all marine aquarium inhabitants!
Guys they cut down on ading trace elements,help feed the corals and the bigger the better
