hey guys, couple more questions...heres my story, I live in a apartment while im at college, and i cant have a larger tank than the one I do (20g). Im very into this hobby and I am trying to make my nano into a more advanced machine...so I was thinking about making a sump, just a small one, like 10g. I mostly want it just for more water and so i can move my heating, temp, hydrometer ect down to the sump...

Your always helpfull...Any ideas????

well a sump is always helpful. It is a good idea to put a sump on every tank. It adds more water to the system which will help keep your water stable. do you need ideas on how to set it up, or what?

I only have space for a 8 to 10 g sump..i have the fluval 105 for up to 25g..so would a 5g sump be worth it??
