A week is recommended for once, each time changing the water 10%. Replacement of fish tank water. Step in the right direction:

From the day before the need to change the water, first enough to replace the amount of fresh water reservoir, the aim is to release chlorine in fresh water, because we use chlorine for unsolicited potable water disinfection. In case of need, then, from as early as two, three days of fresh water reservoir, some friends in the fresh water within the gas wood or gas stone cheer, or accession to the submersible pump system for the water to accelerate the gas exchange.

Pet Xiaobian introduced before the water changes, to a sufficient amount of salt added from the prior storage of fresh water and then mixing, the salt is completely dissolved. The proportion of the specific gravity measurement of the degree of water, the proportion of the best reach 1.022 standard consistent with the fish tank water. In case of need, then, can be as early as two, three days to fresh water mixed with salt accession to the submersible pump system for the water to make the salt is completely dissolved, and strengthen the new dissolved oxygen in seawater.

When changing the water, first need to replace the amount of old water from the tank pumped out and then slowly add new seawater tank, not a son to all new water into the tank, and to avoid the surplus has not been dissolved salt tablets into the tank to make the biological impulse. If sand tank (sump), the process of changing the water should be carried out in the sand tank.
