currently i have a 90 gallon set up and i do not like where the tank is. so i figure why move it when i can upgrade.... 2 options a 125 or a 120..... for lighting i have a 4' current sunpod 2x250 and a 4' current sundail 4x54 t5...... could i run both fixtures over the 120 ..... tank is 24'' across and both fixtures are around 10-12''..... and with the 125 can i run both fixtures using cross bars in the canopy?? obviously the 125 has 2 braces and i need to work around that........is there any problems that im over looking?
