cleaning a diy cloner?

What should I use to clean my 18 site cloner (18 gal)? How often should I do it? I use tap water after I bubble it for 12 hrs to remove chlorine. My pump is for salt water also so I don't know if a cleaning agent would hurt it or not. Thanks

per the directions from my 25 site cloner machine. rinse out all old water, add 1 cap full of bleach, refill to normal level. run for 10 mins. dump out and rinse again. refill to normal level, add 1 capful of hydrogen peroxide. run for 10 mins. dump out. refill to normal level with water only. run for 10 mins. dump out. done. run this with pump and sprayers for all steps.

since its pretty much just a copy of a ez cloner why dont you just read their manual on their unit and see what they recommend?
i just rinse mine out with hot water but when i built mine i never glued the pipes so i could look and clean inside the pipes if needed.
