good point there. if i was going to do flow through systems i could do individual ones for each tank. i like the idea of not having to deal with water changes though, as for water changes there i would be setting up a trough with a sponge filter to filter out alot of water to do changes, and a flow through would be much easier on the fish and me back

i was thinking that i might do a smaller saltwater setup along with the 180's, or possibly just do another 180 for saltwater. in regards to the 180 with piranhas i would do 8 just to give space. ive considered fully getting one BIG tank for pacu's, but to me i tghink id get more out of several 180's with nice setups, and itd still cost less than pacu's in a big tank. and i also thought about getting an arowana as part of this room setup, but i think its tank would be too big and would tank too much advantage of the space. but id like to get a flow through or something that does a constant water change, put me out of alot of stress. i can get a picture back to you later of my idea. cuz if i got that big of a tank, im out of options right there, i get like 2 pacu's and bam, im done, no more room for other fish. and no more room for other tanks as well........ i really think that if i drew it out it would make more sense. posting picture later. tell me what you think of it joe.
p.s. im nowhere near downers grove, i am, but itd be like an hour and half drive or so

im not sure if that lfs would special order for me or not, they might, but i havent asked them yet. another will do
