I am looking at upgrading my skimmer. I currently have a 180 gal tank w/sump. My tank is set up as FOWLR because I've never had the lighting for corals. My LED's will be in tomorrow and am trying to upgrade my equipment to get my Nitrates to 0, they've always been around 20 mainly because of water changes. I am looking for a skimmer with a small footprint, primarily because of the height of my stand. After researching, I have come up with two options both involving a Tunze Skimmer. Now to my question
.
I can purchase a Tunze 9021 for around 590.00. The website also has the Tunze 9010 on closeout for 260.00. So for 520.00 I could purchase 2 of the 9010's and run both in the sump. The 9021 is rated for 554 gal tank and the 9010's are rated for 264 gal tanks.
I don't know if it's wise to run 2 skimmers in the sump or just purchase the more expensive larger one. Any suggestions would be greatly appreciated.
