[arnaldolex]

so i just got a three part doser and and wanna start dosing am at work so cant text my waters now but i know there ok will test on monday so my first question is i have a 125 and 30 gallon sump but i have alot of rocks dont know how much id say over 200 pds am gonna include some pics i got in my phone about how many gallons do ya think i have in my tank also my sump has a euro reef skimmer rated for a 180 foot prints about 10 inches and some algae. how many gallons do ya think i have of water also i read alittle about two part dosing am gonna make my own with pedalow that i usually just dump in my tank and baking soda i have a whole print out on how to do it my question is should i dose half a ml per gallon of both or 1 ml of both in the beginning i figure i will test every two or three days for like two weeks how did ya find out how much to dose

Only dose what is needed. Track your numbers by testing and writing them down to see how much is being used.
Then you can figure out how much you need to dose to maintain your target numbers.

do u think i have more than 75 gallons of water shouldi dose .5ml times 75 of each or 1ml of each i really wanna start dosing but dont wanna make it CRASH HOW DID YA LEARN HOW MUCH TO ADD

Ok. I copied this from Fauna Marin


Example:

50 ml of canister 1 into a 500 litre aquarium.

Value before dosing = 380 mg of calcium. After 2 hours repeat the test ? 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 ? = + 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.

A daily inspection of the calcium (Ca TEST), magnesium (Mg test) and dKH values (KH test) is to be conducted at the start and the dosing quantity adapted on the device if necessary.

Test your Alk and cal. In morning. And Mag. And let us know what your reading are and we will work from there. Every tank is different and it's on how much your corals take each day. This could take a few days to a week and some testing. Also what level you want to maintain.

^^^^

You need to test your water parameters for a few weeks to know exactly what your system depletes on a day to day basis. Even on a 12 hour schedule if you want to get anal. This way you will know what you will need to add in.
Make a spreadsheet. Record your Cal, Alk, Mag losses per day. It will then be easier to calculate your loss from there.
