Hi I'm currently running a very, very basic sump, essentially an undivided 40G breeder with a return pump sitting in a Tupperware bucket. the 65G display tank empties onto a filter pad and carbon housed in a little lee's breeder box. the sump contains live rock and a reef octopus bh2000 skimmer. Some day when I bump up in tank size I may look into a more advanced design but for now its crude but seems to be getting the job done. I would like to take it up a notch by adding some chaeto running counter to display lighting. Can I just add the chaeto and light it up and be good or do I have to worry about chaeto working its way into my display or clogging my return pump? Any imput would be great. thanks Kurt
