Dissolved CO2 is one of the most fundamental nutrients ( gaseous nutrients ) for aquatic plants. Any aquatic plants without CO2 would not be able to grow properly and not able to perform photosynthesis efficiently. It will also halt the reproduction of new plants in the environment. All the plants will deteriorate and eventually decayed. Generally now in the consumer market, to attain CO2 supply, there is the need to equip with bulky CO2 canister tank which is expensive and bulky. Seeing the need of a better solution to CO2 supply, Ocean free has successfully developed a convenient, economical, innovative and practical method of CO2 supply, the CO2 tablets. All is needed is just the administration of the CO2 tablet into the planted tank on daily or by-daily depending on tank size I basis.
Using the latest technology in production, these tablets are able to diffuse slowly and evenly. Through this special release method, a small portion of the bubbling can be seen by the naked eye while the rest of the CO2 is already dissolved in the water. This ensures the aquatic plants to have enough time to absorb the dissolved CO2. This product uses special raw materials that will not alter water PH and would not cause harmful pollution.
