The other question is, and this is directed toward you Denny (and other tank builders and plumbing masters-alike)... could I get away with 3/4" drains in a beananimal configuration (1 full siphon, 2 back ups) and do 600 gph without too many issues?

not sure if one little snail is gonna block 3 different drains at different heights but weirder things have happened lol 600gph isnt alot of flow so im assuming your tank isnt that big right? i cant recall the size though i did read your journal either way i think you would be fine with 3/4" but im a fan of 1 inch or bigger;p especially for the emergency drain. glad the build is getting done fun stuff eh minus other peoples mistakes and all lol
