[new-2-the-reef]

its been almost a month now ,since i've had my tank up and running
today my test result's were


ph level - 8.0-8.2
ammonia- oppm
nitrite- o ppm
nitrate- 20 ..still holding same as last weeks test
salinity /gravity- 1.026
96 pounds now of cured live rock

my first 2 test were as followed after initial set up

around 60 pounds of cured live rock
sept 9th... first full week of set up
ph level-8.2-8.4
ammonia-0.25 ppm
nitrite-o ppm
nitrate-o ppm
salinity gravity-1.032 (i added to much salt )

sept 13th 2nd test
went up to 88 pounds of cured live rock
ph level -8.2
ammonia- o ppm
nitrite- 0ppm
nitrate-20 (first time it went up)
salinity/gravity-1.028 /030


so today after my third test of water quality

I have only had a spike in my nitrate and it has been not to bad according to what i have read and seen on here and in test guide..

my question is should I expect a bigger spike in the next coming weeks at all.....
and when would be a good time to perhaps add some easily priced coral
now or in a few more weeks

thanks guys/gals
