One of the methods for keeping algae away from your aquarium plants is to use the easy estimating index procedure of adding a prescribed amount of nutrients to your tank without having to use any test kits. You have to keep adding the required nutrients on a regular basis so there is no shortfall and change the water every week to prevent saturation. Thus, you can effortlessly sustain a moderate level of nutrients even without having to use a test kit.
However, if you have no time to spare in order to change the water on a weekly basis, here is a simple, quick, effectual and unconventional way of getting rid of algae from your Java moss or any other aquarium moss or aquatic plants you might have.
All you need is bleach and water. Make a mixture of bleach and water in the ratio of 5 parts bleach to 95 parts water in a receptacle. Add the moss. Swirl it around a bit and wait for a couple of minutes. The algae will get bleached if it is of the soft variety. If it is the hardier one like Hair Algae or Black Brush Algae, they will pale in color and eventually die.
Remove the moss from the container and rinse it thoroughly to make sure no traces of bleach are left. Alternatively, you could treat the moss to a solution of anti-bleach in another receptacle. After following these steps you may as well consider your moss to be brand new.
Considering that your aquarium is rampant with algae, bleaching the java moss alone will not eradicate it. This procedure works best for outgrown receptacles you might have for nurturing baby fish. Normally we might add some aquarium moss like Java moss to the receptacle to absorb the surplus nutrients. By the time the young ones (called the fry) have matured, normally the moss would be stricken with algae again.
Dipping in bleach would make the moss usable again. Make sure you bleach the receptacle as well and keep the bleach out of reach of little children. It is poisonous in an undiluted state.
