thanks for that input busterbrown. i think i might do that now. ill probably leave the 60 as is, and just throw them in there or divide it and make it into a sump and put them in that 40 gallon section so its less water for me. so for water changes would you say,
1. i dump the water then when filling fill with the water from 240 then the new water add into the 240 to top that off
2. have the sump (60 gallon) running through the 240 so its less water changes, theoratically because the water is constantly circulating from the 240 to the 60 then back to the 240.
3. have them both completely seperate and do their own water changes and add new water to each tank. not mixing either together
