Question #1: What is a sump and what is its importance for a reef tank?
I have a 20L tank that has been running for four days. Here is the list of specifics: Size:
Millennium 3000 (it has two filter inserts and two bioplates. Turns 200g/hr) Lighting:
Currently just normal florescent.\ Substrate:
Live Sand (1 inch) Live Rock:
8lbs of live rock Heater:
Can't remember. Threw away the box. Temperature:
Several hermits and two snails (I know I should not have put them in till after the cycle and now I know that I won't do it again.)
Sorry for the list of specifics but I figured if they were needed, then there they are. So my question is, should I have a sump? If so, how do I go about making/plumbing one? I have a 10g just sitting around (with water and a running filter) that I was going to use as a 10g freshwater but there is nothing freshwater I really want to keep (I set up the 10g before getting the saltwater). Could I use the 10g as a sump/fuge? How would I do it? and what benefits are there to having a sump that size when you have a 20g?
