Hello Auballagh. I've seen you refer to the 24x48x24 as a 150 XH before but to me it comes out at 120 US gallons and the 48x18x24 at 90 gallons. What am I missing?Auballagh said:Hello Andy,
you may want to measure out this new 110 gallon aquarium you just got. If this aquarium actually measures out at 24"Wide X 48"Long X 24"High, then your tank is the so-called 150 gallon XH. If this tank measures out at 18 inches Wide - then it is the 110 gallon XH.
