Salinity of water in the aquarium, advice

Sarah

Hello, after moving to another office for work, we inherited a small marine aquarium of about 90 liters, which is a bit neglected. First, I measured the salinity of the water, and it shows 1.035, while it should be around 1.023-1.025. How can I lower it to this parameter? The salt used is Tetra, which is probably what was used to salt it.

dilute with osmosis, but not immediately, preferably by drip method

It is very important to control the salinity of the water in the aquarium. Replace the water in the aquarium with dechlorinated fresh water at a temperature close to that of the water in the aquarium. Wait for the water to stabilize, and do not use salt that has already been dissolved in water, as it may contain contaminants or harmful bacteria.
