i have a spare 40 gallon and dont want anymore fish so id like to turn it into a sump for m 55. what would be the best way to do it? is it hard or complicated to drill tanks? about how much would it take to set it up? where would i get the items needed? how long would the 55 have to be empty to drill if i did go that route or are those overflow boxes worth it? i read that with those the flow could be hard to start
the 55 is stocked with one flowerhorn, pleco and 4 danios
