125g wet/dry.......

I'm taking it to mean that whatever company is marketing it claims it to be suitable for 125g tanks. Probably around 20-30g total water volume.

Am I correct?

ya i think your right mike, unless he has this monster wet/dry under a special built stand??

I thought it meant 125g moves through it per hour, but the pump would also contribute to that.....

oh yeah sorry about that.. no it's not 125 gal. wet/dry system. but it's suitable for up to a 125gal tank.

what is the purpose for having a refugiam. and whats the rule of thumb or size that i need for a 75 gal.

A fuge is a specific space for certain types of life form to thrive. Thee lifeforms are typically unwanted in display tanks. The purpose is to allow them to thrive out of sight with the intent to lower the amount of available nutrition to their counterparts in the display, effectively starving unwanted pests to death. You'll see people use fast growing algaes that are easy to harvest. Mangrove pods as they will leech out nutrients and store them in their leaves. Some have tried refugiums full of mussels from HEB, clams from the beach, or oysters. I've heard of several full of Xenia or Aptasia. SOme people stuff them full of bristleworms.

Others choose to add them for reasons of providing a place to grow out food items for the display tank such as copepods.

I'd say 20g is plenty of tank for a 75g. I keep my light on at 24W 24 hours a day. Doing so helps prevent a shift in CO2 generation.shutdown that can cause a sharp change in PH levels. Some run there lighting alternate to the display to keep down the costs, etc...

So in review there are no hard and fast rules. Read up on several different "theories" (as it's all just theory anyways) and decide what is right for you and what you want to experiment with.

thanks for the explanation Caferacermike about the refugium. that is really helpful and thanks for taking your time, now i suppose that the water from main display should cycle through the refuge, do u know of any website i can go to, to check out some displays.
