coral chip exhuastion

[error]

Hi, coral chip contributes hardness and increase pH in water.
My question is that; do they exhaust like natural water softener etc. peat, ketapang leaves.

I dont think so, unless you can get the whole coral chip 'melted'.

Hi Silane,

When and how should we apply calcium for my CRS?
My GH is <30ppm, KH is 0ppm.

Forgot to tell you, i do have a old sea mud rock inside, but wonder if it contributes calcium and inportant mineral for CRS.

I have the same water parameters than Error:

Kh<1
Gh 3-4

Should I add anything? I would like to hear if any of you had breed CRS in such conditions

Thanks.

hi, dont expect much.
it has been months, there is still no breeding happens.... sad.

My CRS took a month or two to begin breeding. Im sure it wont be long.

My tank was at KH of 3, GH of 3. Now I have changed substrate and my KH is 0 too and my PH is going low < 6. I will be adding baking soda (sodium bicarbonate) to keep my KH around 1-2 and PH 6.5.
I add seachem equalibrium also which helps with calcium and will also raise KH/GH a bit.
