Hi,
I have just grabbed a bargain, a Luminaire twin 54w T5 4ft for £13. Currently i have a hood with twin38w t8`s and i`m concerned that when i switch to the T5`s i`m going to have an algae outbreak. For the past 4 months going by CEG`s advice i have had zero algae and growth has been good apart from straggly stem plants which i suspect was a lack of light. So i`m hoping raising this lighting level up to T5`s i`ll finally be able to grow decent stem plants. The 4ft tank it`s on is high EI dosed with 30ppm (ish) of injected co2. Should i reduce the photo period for a while when i get the new light? Should i change any of my existing regimen (2x trace 3x npk per week), co2 @ 3b/sec, lights on for 12hrs a day?
Cheers,
