| thanks for the diagram, really appreciate it! more questions, what is a refugium (I understand it's another type of sump set-up)? what is a detritus? why do I need to keep the refugium from being the most effective? I was thingking of getting a MAG 12 for my return pump (about 950 gph). what is a close loop?
thank you for taking your time answering my questions.
I really appreciate it! |
