Bruce has GROWN! Lights are cool too! Which one did you end up settling on?
Still, I'd go ahead and plant the tank as quickly as possible and slowly work up the tank to a full light cycle[however long that is for you]. Believe me, if they're T5HOs, you'd get algae faster then anything if you're not careful but they are EPIC at growing plants!
Bruce is totally happy to have so much room. He was starting to be a brat to the other fish, being couped up in the 10 gallon. I didn't think it'd take to so long to get this tank up :/ But it's up now and I'm happyYour tank is looking really good. I bet Bruce thinks he's in heaven right now.
