I ask as I have just got delivery of an overhead LED system and it is surprisingly bright. It is in fact brighter than the existing tube which is integrated into the aquarium hood. now I had in mind to send this LED back but I am now having second thoughts. I want a planted tank so am I better off sticking with tubes? I have some t5 ho tubes coming soon? The tank is 20 gallon. Would LED result in poor plant growth?
