How to solve the bubbles in the aquarium?

1. During the design of the life support system, it is necessary to degass and mix the water produced by the additional degassing tower, sand filter and protein separator in the degassing tower. At the same time, there is a fan in the degassing tower that contacts with the reverse air inlet to discharge the volatile gas in the water from the system, and at the same time, increase the contact between oxygen in the air and water, and increase the dissolved oxygen in the water.
2. The water in the degassing tower flows to the display tank by itself through the water level difference, and bubbles cannot enter the display tank because these pipes are at a lower position.
1、 The aquarium marine engineering packaging landscape engineering construction room exhibition pool or fish tank construction is completed, and the water test is qualified. 100mm concrete cushion shall be made at the bottom of the pool to prevent damage during packaging construction. The construction scheme of the aquarium marine engineering package has been approved by the owner.
2、 The aquarium marine engineering packaging and beautification engineering technology requires that all materials shall not be toxic to prevent poisoning of animals in the exhibition pool. Metal materials shall not be used for the marine engineering packaging and landscaping engineering materials of the aquarium, so as to avoid fish poisoning due to the dissolution of heavy metals in the metal materials.
