Your tank is 24" x 18" x 15" tall.
You should be looking for a 24" long 2 x t5ho at 24w each fixture. That will give you relatively high light, especially if each bulb has it's own reflector.
The first fixture lists the bulb's output at 18w each.
The wind fixture lists the bulbs at 12,000K, which is a bit high for a Plantex tank. I would look for bulbs in the 5,000K to 7,000K range.
