ok i've got a 75 gallon coming that is going to be the masterpiece of the front room, right now i have a 29 gallon that's going to saltwater (brackish setup now for my mono and puffer) and a 10 gallon FW but i want to upgrade the 10 gallon since i'm going with saltwater for the seventy five gallon. i can get a starter kit for $69.99 for a 20 gallon or $99.99 for a 29 gallon. i have a stand for the 20, which my 10 sits on now that made for either. do you think for 30 bucks i should go with the bigger tank? since i'm going to only have one freshwater tank, i was thinking that the 29 would be the best bet. Also walmart has a clearance on their 29 gallon stands for $45.00 cut down from $69.00. any suggestions?
