First off, apologies if this has been covered elsewhere... I am in the process of setting up a new tank, which i plan to be planted... It is a fluval roma 240 and eventually I plan to take it high tech (all pond solutions do a great 4 tube t5 luminaire for a reasonable price- i have one on my lido 125...) but until i can afford that i will be sticking with the stock lighting which is 2 42W t8s... Tubes supplied are aqua-glo and power-glo... both of these are 18000K tubes, which i am led to believe are not ideal for freshwater... what tube combination would you recommend to make the most of my meagre 80 watts?
Thanks for your help
