If you are entertaining following the PMDD (Poor Man's Dupla Drops) regimen, understand that it is different from the one I mentioned, using nutrient limitations to suppres algae. The one I gave, basically prescribes providing all nutrients, with high dosing *and* water changes to control levels. Also, keep ahead of algae growth or it will get ahead of you. That is, clean regularly as you find it and it should always be a small task. Let it go and it can get out of control, especially in a high light tank. If your plants are flourishing with good nutrient levels, algae should be minimal. Good luck, have fun, Scott H. __________________________________ Do you Yahoo!? SBC Yahoo!
