CaribSea Arag-Alive 20-Pound Special Grade Reef Sand, Fiji Pink by Carib Sea

muy buena opción si quieres reducir el tiempo de ciclado en un acuario, ojo reducir, no te da un acuario ciclado automáticamente, pero si ayuda a que este se estabilice más rápido, la arena es muy fina así que no la recomendaría si quieren tener especímenes muy grandes tales como rayas o tiburones, ya que esta con el movimiento se mueven fácilmente pero en sí es una muy buena arena la cual se agradece que venga con bacterias y más aparte incluye un sobre con un líquido a que ayuda a que al introducirla la arena dispersa en el agua se asiente 10/10

Looks really great in the tank can't wait to get fish in there

great sand!! thank you. no need to rinse with rodi water. cloudy water will go away fast if and only if floss is used. both of the nano tank water cleared in about one day. the cloudy water is really crushed sand. the sand is crushed during packaging and shipping. no need for reef carbon, purigen and phosguard when cycling new aquarium. some people use dry sand and dry rocks to start a new saltwater aquarium. please do test the aquarium water for nitrites, nitrates and ammonia for two months. the dry rock, dry sand method will take 60 days for the aquarium to cycle. then add filter media and cleanup crew ie. snails to the saltwater tank. make sure ammonia is zero before adding fish and cleanup crew. some hobbyists use real saltwater, live rocks and live sand. add add benificial bacteria with fritz turbo start 900 will help either way. both our tanks cycled fast with live rocks, live sand and real ocean water. livestock was added a few days later. and only after testing the aquarium water to ensure the aquariums was safe for fishes and a cleanup crew. both pairs of black snowflake extreme clownfish love it in their nano tanks. we used caribsea fiji pink sand and live rocks with plenty of coralline in the two nano tanks. coralline are the purple algae on the live rocks. coralline algae comes in many colors such as pink and purple. aquarium lights such as kessil are great for live rocks and coral, however, only ambient room lights are currently used to light both aquariums. the purple coralline on the live rocks will get lighter in color and the purple and pink colors in all likelyhood will fade without aquarium lights, however, the helpful and needed bacteria will still be alive. never leave the aquarium lights on for extended periods of time. do not keep the aquarium lights on for too long a period of time. in addition, overfeeding will cause the aquarium water to be nutrient rich for green hair algae, algae and cynobacteria better known as red slime algae. all saltwater aquariums have ugly stages. some hobbyists use a uv sterilizer to help with algae and ich. patience is needed for this hobby. water tests and at least three months are needed before adding easy corals. never introduce too many fishes to an aquarium. always do weekly or biweekly water changes. always use rodi water to topoff the evaporated water in the aquarium. never use tap water for aquarium water evaporation. always go slow. and read and post questions in saltwater aquarium forums.

Ce sable rose Fidji fais un effet super beau avec la lumière de l’aquarium qui reflète dessus ,, ça vaut la peine et il est blanc avec un léger reflet rosé très léger mais de toute beauté

I had ordered 2 bags but got 1...good thing is they refunded the amount for 1 bag within a week. It's been just a month now and the CARIB SEA Aragonite alive reef sand seems to have started doing its job perfectly. I had mixed it with dead sand which it has been slowly turning to live. The appearance is unique and very appealing. Pros: It suppressed the new tank syndrome, reduced ammonia, natural filter. The water is clean and crystal clear. The best part provided lots of surface area for bacterial adhesion. Cons: None I would recommend this product a must buy for all reef/saltwater tanks. My tank dimension: 42X16X18 (inches) FYI: 1 bag was enough to attain a depth of 1.5 inch ( I had mixed it with dead sand. 22lbs Carib sea sand + 7 lbs of Dead sand)
