- PVC polymer of non-migratory nature should be used in a biofloc fish tank. Sub-standard PVC coating has a migratory nature which tends to dissolve in water and has a very detrimental effect on the growth and survival of fish.
- The thickness of the tarpaulin sheet should be optimum i.e., 600 GSM± 10%. This is the international standard followed throughout the world. Most of the biofloc farms in Indonesia; Mecca etc is using more than equal to 600 GSM Fabric.
- The tank should be welded with 3D technology with a state of art Seamtek machine from Switzerland. Other machines' welding will not sustain the continuous pressure of water resulting in water leakage.
- Transparent PVC Film should be used to reinforce all the joints to withstand water pressure and provide long life.
- No wrinkle should not be present in the tank. Wrinkles accumulate ammonia and cause toxicity to the fish. Accumulation of ammonia means the stopping of the biofloc cycle.
- All good quality PVC tarpaulin fish tanks come with a written warranty of 05 years with an expected life span of 10 years.
- The PVC tank should be hemmed and reinforced with a 10mm PP Rope for extra strength on the periphery of the tank.
- Light color like sky blue Colour of the fish tank is better for working easily (better visibility of fish and accumulated sludge).
- While installing a tarpaulin biofloc tank, a Protective HDPE liner should be used for increasing the life of the fish tank.
The shed should be used for:
- To prevent sunlight to reach your tank
- To prevent algal growth in the biofloc tank
- To protect fishes from birds and other predators
- To prevent falling of leaves or other debris from the surroundings etc
- To enhance the life of the PVC tarpaulin fish tank
