Hi all, I'm now trying to start a planted tank after come to decision to throw away my plastis plants! Having been an avid reader on this forum for sometime now, I guess I'm happy to take the plunge now and see how it goes. Anyway, I've got 2 of these came from the tank: http://www.aquatics-online.co.uk/catalogue/interpet-aq3-complete-aquarium-spares.asp, but 1 is blue! I was wondering whether they count as the WPG rules as not sure are they categorised as Compact or not? Also, not really sure what are the K ratings as not really specified in the packaging. Another question is that, can I buy a normal Daylight bulb (6400K) to replace the blue one? FYI, the tank is 60L. Thanks.
