Ok thanks, this sump layout might work out for me - thanks!
How much room should I allot for the return compartment? I thought it would be small as it only accommodates the pump but then I read for various reasons it's sometimes the biggest. I'd like the refugium to be a good size though.
Question: Is there a way to remove the old plumbing going into the tank? Here's the old return with the plumbing sawed off. Is it in there for good, and we have to attach new pipe to it, or is there a way to get it off?
Same question for the other 2 pipes. I guess you can see it was a Herbie system in the far corner.
Thanks!
