Algae Based Systems
These systems use very long runs of clear vinyl tubing and specific frequency light to grow and maintain beneficial Algae that can even convert and eliminate Nitrates and other trace elements from the water. Manufacturers claim that these systems are so efficient that a single 25% water change is all thats required per YEAR Mechanical filtration is handled by a simple pre-filter and the whole thing runs on a very low draw pump.
Can you tell me how to do that it sound interesting
