[shrimpchips]

What's the size of your tank, fish (and size), skimmer, lighting (how old are the bulbs, photoperiod), flow in side tank, feeding schedule (and what you feed)? These will be important determinants of algae problems too. Also, how long has your system been set up?

What brand of salt are you using?

Are you using RO/DI water?

Also, if anything, switch to larger weekly water changes.
