Example:
50 ml of canister 1 into a 500 litre aquarium.
Value before dosing = 380 mg of calcium. After 2 hours repeat the test à the calcium value after the 2nd test is then 400 mg of calcium.
In this example 50 ml of the solution from canister 1 increases the calcium value by 20 mg/litre for a 500 litre aquarium.
Now programme the dosing computer to add 7 ml of the solution once a day, i.e. 50 ml of the solution spread over a week.
After a week measure the calcium value again and note it has only risen to 390 mg/litre, although in a pure arithmetic sense this should have risen to 400 mg/litre.
This method determines the actual loss of calcium in the system that is to be compensated. In some cases this actual loss may differ significantly from the calculated loss as a result of growth or chemical precipitation!
You can now easily adapt the dosage level by increasing the
value by 3 ml per day as already calculated. 50 ml à = + 20 mg / 7 days = 7 ml
In order to obtain + 30 mg therefore 75 ml / 7 days = 10 ml must be added.
Using this simple 3-part calculation you can easily adjust each of your desired values and set an automatic dosing schedule in just a few days.
