I am setting up a 20 long to grow out some frags. I will use water from my100 to get it going. I will not be using a sump, just a ang on filter. I have two questions......how long should it take to cycle if I use cycled water and live rock from my other tank? How will I prevent algae in the frag tank without a sump? I can look for a small sump if that is my best option.


I will be using a t5 stip and a 20" mh



Thanks

Jeremy
