Got some plants from Andre (thanks Andre! ) from a tank invested with Cladophora algae. I've treated the plants with 1 part to 20 solution of bleach to water for 2 minutes, followed by a thorough rinse in tap water, then a soak in water with dechlorinator for about an hour, another rinse, and then placed in a container with tank water and seachem excell at higher than usual dose. Its been about 3 days now and the cladophora is showing no signs of dying. Should I leave it for longer, or treat with a higher dose of bleach? The plants are still OK, but I don't want to kill them either.
