Sell PSB KING Photosynthetic Bacteria For Marine and Freshwater Aquaculture best price

Produce by sampling natural and unpolluted evironments, as well as pure line cultures in the laboratory ; does not contain heavy metals or chemical pollution. Contains Pure PSB Photosynthesis bacteria Photosynthetic bacteria(PSB) is energy heterotrophic bacteria .Under the aerobic dark and anaerobic light conditions, the photosynthetic bacteria uses the organic matter in water as their breed source of nutrition and rapidly decomposes the harmful substances in water, such as ammonia nitrogen, nitrite, hydrogen sulfide etc.It can also fully decomposes the feces and bait of aquatic animals,Which can protects and purifies the culture water quality and provides a very favorable environment for the life and growth of aquatic animals.Photosynthetic bacteria with special nutrition can promote growth .It has disease resistance factors, high-efficiency purification capacity of farming sewage and innocuity on the environment and aquatic animals, which is widely used in water treatment and animal breeding areas. When added on a daily basis, it actually increases the metabolism rate of the fish, and the fish is more active. For Marine and Freshwater Aquaculture Directions for use ; Add 2-3 ml every 100 litres of aquarium water, shake well before use. Add the PSB bacteria 1-2 times every 7 – 10 day or during every additional of new fish or after every water change . Pay Attention: DON'T OVERDOSE Expired Date 1 Years Store Under normal Light . Method for quality identification of photosynthetic bacteria 1. The appearance is relatively uniform, and there is basically no stratification. On the contrary, many photosynthetic bacteria on the market are layered up and down, the upper layer is lighter, the lower layer is thicker, the upper layer is lighter in color, the lower layer is darker in color, and there may be a layer of black precipitation at the bottom. 2. No sticking to the wall. 3. The depth of the color is relatively deep. According to national quality standards, a 721 spectrophotometer can be used to measure the absorbance at A660nm. If it is greater than 1.5, it means that the concentration is generally above 3 billion / ml, and good photosynthetic bacterial species and products are above 1.5. 4. Bright colors. Excellent strains and products are not only dark in color, but also relatively bright, such as red, blood red, or dark purple, it looks very pleasing, or dark colour. 5. PH value. Mature photosynthetic bacteria are alkaline, with a PH value above 8.5 and a certain buffering capacity. Dropping a few drops of edible acetic acid makes the PH value of the bacterial solution drop below 8.0. After a period of light, the PH value will return to the previous value. 6. Smelly urine but not Rotten smell. Use On marine will 7. Identification from expansion. High Quality photosynthetic bacteria that meet all of the above attributes sure wil
