Bacteria break down the shrimps' wastes. The breakdown products provide nutrients to the algae and bacteria upon which the shrimp feed. The manufacturer states that shrimp live in the EcoSphere for an average of 2 to 3 years, and are known to live over 10 years. A magnetic scrubber is enclosed in each EcoSphere. By passing another magnet over the outside of the glass, the owner can manipulate the scrubber to clean the inside of the EcoSphere.
Some panels have been known to still be more than 80% efficient by the end of their life. With care and attention, solar panels could potentially last over forty years after installation, although their performance will have deteriorated marginally over that time. The 40-50 year life expectancy goes for both monocrystalline and polycrystalline solar panels. Less is known about the lifespan of thin film panels at the moment but, as they also have 25 year warranties as standard, they are expected to match the long life of crystalline panels.
