High dKH, Mg and Ca. How to reduce?

[Jameshong]

Hi,

I just tested my water parameter and surprisely the Mg, dKH and Ca are at the high side .

How am i going to reduce it to the ideal level? I'm using Oceanic Natural Sea salt with a tank size of 3*2*2.5 ft. Tank housed 5 MIs, 5 gobies(3types), 3 stars and 5 turbo snails.

My Parameter:

Specific Gravity 1.023

Temperature 26°C

pH 8.2

Alkalinity 17 dKH

Ammonia (NH3) Undetectable

Nitrite (NO2) Undetectable

Nitrate NO3) 10 ppm

Phosphate (PO4) 0.1 ppm

Calcium 480 ppm

Magnesium 1700 ppm

Btw, how to reduce the NO3 to undetectable har !

gradual and substantial water change shld do the job.

and perhaps a refugium will help alot too

we have opp problem

Ha...ha..ha..zephyros,

I think we should exchange the tank water so that it will balance up for both of us lol .

Btw, do anyone know how to reduce NO3 from 10ppm to 0 ?

or it's ok for NO3 to be 10ppm ?

it is still in the tolerable zone but like I said add a refugium with a DSB and perhaps add more plants in it too!!!

Hi Panzz,

My main tank setup is a DSB with 80Kg LR,but w/o any plant.All Live rock and sand is from my 3 years old tank at my old house .

There is a small sump below the tank, but mainly it is for the Skimmer, chiller's pump filtering material only.

It is a new setup about two months plus, hopefully the NO3 will gradually reduce to 0 lol.
