Juwel light units?

[Vikkiog]

Hey guys just a quick question. Got a juwel rio 240 second hand which is about 4 years old and was just wondering if anyone knew if it would be t5 or t8 lights? The bulbs in there at the moment are aquaglo 40w 107cm which apparently haven't been changed in years :/ and I can't read the writing/stickers on the unit itself.

One more also: one of the bulbs makes the fish look red/purple when they get close to the surface. Is this alright or would a white/day bulb be better? Thanks.
