Adjust salt level accordingly.
Instant ocean reef crystals levels.
If specific gravity is too low add more instant ocean.
If too high add more dechlorinated water.
Instant ocean is formulated to provide a solution with levels of calcium and magnesium found in natural seawater nsw assuming you use purified water to dissolve the sea salt.
Change 20 of aquarium water every two weeks to maintain optimum water quality.
My theory is that instant ocean knows there is going to be precipitation so they include enough extra of each element to allow for precipitation while still providing elevated levels of each.
If specific gravity is too low add more reef crystals salt.
Tightly reseal bag to keep out moisture.
Lf too high add more dechlorinated water.
Recommended specific gravity range.
Recommended specific gravity range.
Every batch of reef crystals i ve tested after a minimum of 24 hours still contained high levels of alk cal and mag.
Tap water most often contains dissolved calcium magnesium and other minerals that will add to the levels provided by instant ocean.
1 4 lbs of reef crystals is formulated to create 5 gallons of saltwater at a specific gravity of 1 021.
1 020 to 1 023 at 75 f.
1 5 lbs of instant ocean is formulated to create 5 gallons of saltwater at a specific gravity of 1 022.
However testing after a water change yielded these results.
Measure specific gravity with an instant ocean hydrometer.
