Set for reducing Aiptasia

Possibilities for exterminating unwanted animals:

1. We only can dissuade from mechanical techniques. With nearly all common techniques the animals are destroyed but the remains will breed very fast new animals. But now they are allocated in the whole tank. 
2. The most simple method to arrest Aiptasia is to introduce Aiptasia-eating animals. Unfortunately only a few animals are eating them. Most of them are eating other corals, too, or they do not take them if other delicacies are served. Or the biological struggler becomes to large with the time and is not suitable for normal coral tanks. Other animals you do not get in the shops or some animals are only eating Aiptasia and if they have destroyed their food completely the will die. But the Aiptasia will come back!
3. To destroy Aiptasia with hydrochloric acid never use solutions with more the 10%. Fill a syringe with the acid and prick the canula into the animal. Push some acid into its body. You must care to the pH value very carefully. If the pH drops below 7.5 you must stop at once. In water with low KH value the pH will fall off very fast. Do not use other acids like phosphoric acid, sulphuric acid or organic acids. The first two acids are extremely dangerous in handling and organic acids can cause bacteria bloom. 
4. You can destroy Aiptasia with calcium hydroxide. With a very large canula it is possible to prick into the body of Aiptasia and push the pulp into this animal. Aiptasia will contract but it will die. But you have to take care of the pH value, too.
