Your water may be too hard. What is your GH and KH?

[aminyassien]

thanks
no3 = less than 10/1000
no2 = nothing
gh = 8 d
kh = 20 d
ph = 7.2

cl2 = 0

waiting for your kind reply

[aminyassien]

yup. water's too hard.
what should i do in this case ?
please advise

you would have to mix your tapwater with reverse osmosis water. Use more RO than tapwater I think. Usually GH is higher than KH, did you test with drops of liquid or with teststrips?
