Have 140gal reef tank with 40gal sump,with sand and rock about 150gals total.I am looking a at a AquaMaxx ConeS Q-3 In-Sump Protein Skimmer or AquaMaxx EcoMaxx EM300 In-Sump Protein Skimmer. Which is the better choice and why? Also any other ideas for skimmer under $500 ,best for the money. Choices I have look at Avast CS1 Cone Skimmer, Coral box 190, Coral box cloud 9. Thanks
