I have a large tank, ...almost 1000ltrs and 4 T5 lights. Due to having mixed cichlids and oddballs I cannot have real plants and therefore stick with high grade silk plants. Unfortunately, after a while, they start getting green algae growing on them, I just wondered how you deal with cleaning such plants and whether anyone has found a special way of doing it? I have spent around £110 on the plants, due in part to the size of the tank and do not really want to be replacing them every other month or so.
