Question on dosage

[stevensim]

Hi All,

Any kind bro can help me with how much of these Fert. should I add ?
MgSO47H2o & CaCl2 ? and also what does this do ?

My tank is a 90 x 45 x 60.

I have try to used the Chuck calculator to try out but it is telling me to dose 2.5 teaspoon for the MgSO47H2O to acheive 5ppm and none on the CaCl2.

Thanks in advance.

Errr...

I believed no or very people add these two.
It is because if you are consistent with the water change, the new water added will provide sufficient of it.

I don't think you need to dose Mg, Ca and Cl unless they are not replenished through water change, fish food or coral chips. Your GH will tell you whether you have enough.

Hi Bro Geoffrey,

Thanks, will measure the GH. But what is the value I need to get ?

Generally 3 degrees or about ~50ppm.

Adding CaCl2 and Mg SO4 would not hurt, but it will nto help either if it's this high or higher.
