Rest your wrist to give it time to heal. You may find that, depending on the severity of the sprain, immobilization through a soft cast is necessary. If your sprain is the result of a sports injury, you should stop playing the sport immediately, at least for a few weeks while your wrist heals.
Water also has a high level of surface tension. This means that the molecules on the surface of the water are not surrounded by similar molecules on all sides, so they're being pulled only by cohesion from other molecules deep inside. These molecules cohere to each other strongly but adhere to the other medium weakly.
The next question you have to answer is, Are the bubbles a problem?. Some amount of bubbles on the surface of a fish tank are normal, especially in tanks that have air-driven filters, decorative air stones, or have a hanging power filter and a low water line.ometimes the natural properties of your source water (what impurities are in it) will increase the surface tension of the water. In other cases, over feeding, insufficient filter maintenance, or insufficient water changes can lead to changes in the water that will increase surface tension.
