Injecting is more comfortable with short, thin needles. That's why BD has developed the Nano...their smallest needle ever. At just 4mm, the BD Nano (Case of 6 Boxes of 90/bx) is clinically proven to be as effective as longer needles for people of all sizes. BD is the only brand of pen needles you will ever need.
Unlike the Chinese Algae Eaters the Siamese Algae Eaters will eat lots of algae. The more common Chinese Algae Eater stops eating algae as it grows larger, becomes aggressive, and annoys other fish. Minimum tank size for a pair of adult Siamese Algae Eaters is 100 liters (25 gallons).
Containing chlorophyll, algae utilizes photosynthesis to grow. That is, they take in carbon dioxide and expend oxygen as a byproduct. Algae can grow in the shade or sun, but most pool algae strains need some light to grow. Algae need food to survive, and in a swimming pool there is no shortage of tasty food for algae. Nearly every contaminant or windblown speck of dust can feed pool algae. In pools with high bather count, or pools with high levels of debris or dissolved solids, algae has a smorgasbord of nutritious food.
