[isaac1]

Hey guys I'm putting my 1.5 year old 35gallon reef and 6 year old 60 gallon reef into my brand new 80 gallon I've filled the 80 up with water and sand I'm just running a power head in it to circulate I have lights for it but I won't be setting them up untill the weekend when I can install a gfi outlet my biggest question my 60 I picked up off a buddy because he had his tank crash twice from not being able to keep up with the maintence and so theres not much on the rocks except for green hair and aptsia every where so I was wondering if I should slowly add the rock or just add it all at once like witch way will mature the new system quicker I'm not planing on adding any of my 35 untill I'm positive the water is perstine
