What can I do to lower my nitrates?
Tank has been running for about 6 months since I purchased and relocated.
I currently have (6) fish, and am adding my (7th), and final fish tomorrow, which is why I want to address this issue as soon as possible, as I understand that I am riding the overstocked line for a 54 gallon tank.
In the time I have had this set-up, I only started testing myself about a month ago, previous to that, it was weekly tested at my LFS
, and I got the "All Good" response.
I really couldn't tell you what all good was, as the only thing I was testing myself was salinity. At the time, the LFS
was only checking the basics as I hadn't gotten into corals yet.
I have ALWAYS done weekly water changes every Monday ranging from 15-25% each time. In every case, I have tested my water previous to and after the pwc
. My rolling issue is that my nitrates last week hit an all time low of 20ppm, which is not really low at all. This week after doing another 25% (11 gallons for a 54 gallon tank) water change, the trates are at 30-40ppm. Guess what they were before the pwc
? Yup 30-40ppm.
I am using an API kit to test.
At this time I do not have a skimmer. I have 80-100lbs of LR
in the DT, and another 20 lbs in the sump. Also no chaeto or other macro's down there.
Any suggestions would be welcomed.
