Kath, I sell corals regularly online and this chemi-clean really does work. It will not affect any single coral you have in your tank except for your skimmer. There's a description on how to use it including how and when to turn your skimmer off.Thanks. Will look for it locally first then try marinedepot.
Oh no..no. but i wish. lolz marinedepot has been a good source of supplies for me eversince.Is marine depot your site? I have a nano, so.....no skimmer.
