Floating plants seem to do a good job of helping cut back on algae from what I have seen. Specifically water lettuce or water hyacinth if you have the room for it and are willing to keep pulling the stuff out as it multiplies, and it does multiply quickly. Duck weed works too, but, can be a problem with back filters. Outside of these plants I have found draining the tank and leaving it empty seems to work well too.....

Growing old is inevitable; growing up is optional. -- Paul M Wallace <pwallace@u.washington.edu> wrote: John: It has been several years since I had green water(result of a pH down product) and it seems that GW is aggravated by ammonia. With that said you probably have an imbalance of nutrients. The good news is that when balance is restored, the GW will go away. So I am curious about your water parameters. How much light, are you adding carbon or nutrients? -Paul In the past few weeks, I've had an algae problem as well. Rather than coating any surfaces, it simply turns my water green. While it is a pretty color, I am unable to see anything more than about 4-5 inches from the glass. I've added two filters to the original filter. The pleated paper filter that came with the Magnum canister filter, and that I was told would turn water crystal clear, has not filtered out anything, so it must be only a few microns in size. Besides the magnum filter, I have a Magnum HOT, and a Marineland Emperor with Bio-wheel. At first I changed the water every day or two and added a bit of salt, thinking that would slow the growth of algae, but since that did not show much improvement, I decided to wait it out. Any recommendations would be helpful. Anita recommended getting tiny organisms that would eat the algae. Fortunately, the fish seem to be doing alright. Thank you, John It is the tank where I put most of the plants I got at the plant sale as well. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
