My goals for today is, Using a hydrometer, making fresh water which has a specific gravity of 1.000, sea water which has a specific gravity of 1.024, make a specific water with a gravity of 1.006 to 1.008.
First we put the gravel that had bacteria on it. Next we chose a rock with algae on it. Third, we mixed the salt with the normal water. Fourth, we measured the hydrometer in the water it was 1.008. Then,we had to fill the cup halfway with the water we used. Last, there is how you make brackish water using a hydrometer.
