hi ive read that 2# t5HO lights running the length of my 750l(200x60x60cm) tank will grow anything but and iv also read it wont be enough and its still in the low light range. if using the wpg rule i still need .75 watts per gal but is my tank large enough for that to be useless anyway im still messing a bout with ferts filtration and water flow so its hard to tell if there working ive put some LEDS (100 watts) on as well to try and up the watts the thing is im very impatient and want my plants to grow now (i know not good in this hobby) i have a red plant i got from a garden centres aquatic section with no label so i don't know what it is it seems to be doing ok if not slowly is it true red plants need more lights ive read a lot about t5s but cant seem make sense of it i want high/med light because i want fast growth i just dont want to waste any money does any one think .8 wpg gal is anywhere near enough thanks for your help
