need Nitrate help

[bclark7169]

I have a 45 gallon has been set up for about 2 months now. I added live sand (store bought) and about 20 pounds of established live rock, and did 30 gallon water change on my 210 gallon system. I added the 30 gallons to the tank and added 20 more gallons of fresh saltwater to this tank. I can't get the nitrates below 40. I have tested with several different name brand kits and get close to the same reading.. I have done several 5 gallon water changes and a few 10 gallon water changes and even one 20 gallon water change. there is no livestock in this tank just water, sand and rock. I even put a filter sock of Seachems denitrate in the sump to try and help and it dropped maybe to around 35... and I use seachem reef salt..also have a aquac remora running on it for about a month..
Anyone have any ideas on what to try next???
sal. 1.025
nirites-0
amonia-0

also the only light on it is a coralife pc light..algae was starting to grow so i have turned the light off..was starting to get some brown algae and some red and bright green algae growth..

What was the nitrate reading in the tank you took the water from?

I don't suggest re-using water. The beneficial bacteria are not really found in the water column but on surfaces (rock, sand etc.)

It will take some weeks for the De*Nitrate to do its thing. Did you soak it in Stability first? If not, you can try some Stability in the tank but the best long-term solution is some aggressive (read: small but frequent) water changes to get the nitrates diluted out and exported.

It's also possible that the established rock had already become a nutrient sink, and that stuff is leaching back out into the water column... same Rx as above... dilute dilute dilute.
