Not really, you're looking for around a 2 watt per gallon minimum, higher if you're using CO2 as a rule of thumb (and of course for every rule I suppose thereare exceptions but it's served most well) Troy -----Original Message----- From: aga-member-bounces@thekrib.com [mailto:aga-member-bounces@thekrib.com]On Behalf Of Noel Wise Sent: Monday, September 13, 2004 4:19 PM To: aga-member@thekrib.com Subject: [AGA-Member] Aquarium Lighting Thank you for the services you provide to aquarists world-wide. Despite researching "Lighting," I am still in the dark and somewhat confused. I have a 50 gallon tank (36x15x20 ins) lit by a single 30 inch "Power-Glow" high intensity florescent aquarium lamp -110 Lux-25 watts. Is this adequate for good plant growth? Please advise. - Noel Wise (Calgary, Canada) _______________________________________________ AGA-Member mailing list AGA-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/aga-member --- Incoming mail is certified Virus Free.
