I got an offer to buy a 180 100 and 60
gal tanks today for $120 the only problem is I got 2 tanks set up inside 2 outside being leak tested that I built and if I get these ill have 3 more I love with my girlfriends mum so ill have to put it past her I was thinking of scrapping my 55 and new 20
gal and running the 180 with the 100 as a sump hopefully they will agree on this as I will only have one tank then

what would you do?
