75 gallon nitrates.

I bought a bag of chemipure and chemipure elite I'm gonna add both to my sump When I get home from work. Trying to lower nights from 80. Also going to do a water change Sunday morning.

I'd do a couple of big water changes. Also, do you know what caused the spike? You'll need to figure that out to solve the problem. Could it be that something died in your tank?

It's been like this without anything dying. Steady at 80. I haven't seen my dwg in 2 days. He might have gone missing recently. Hopefully not though.

Nothing is better at reducing nitrates than water changes. Good skimming comes in second.

What test kit are you using? API kits always seem to read high. Also, how long has this tank been up? If nothing has died and your test is correct, I'm just helping to search for an answer.

Couple things for you to do. Clean up the detritus in the tank, try and get where it has collected. Hopefully your skimmer is close to twice your water volume, or its not doing its job up to par.
How oftern are you doing water changes? How much are you changing at a time? In order for you to knock down that high of a number fast would be to do 50% water several days in a row. Keeping in mind that the NItrates number should fall by half each time you do that water change.
If your Chemipure and Purigen don't make you happy there is always Vodak Dosing (aka Carbon Dosing)

High nitrates are caused by excess nutrients in water column. Most of the time it is caused by overfeeding. Like others have said water changes, protein skimming will help bring levels down. Carbon dosing as stated by Reefing Madness is a great way to keep trates and phosphates in check.

Ya my problem was 2-3 deads snail black water came out of it when I took them out

Would 20g water changes a week help bring nitrates down?? Can't afford a new skimmer right now.

 

[Reefing Madness]

20g water changes a week will affect Nitrates, but it will take along time to bring them down that way. It would be like chasing your tail, because your adding Nitrates to your tank, they build back up in a weeks time frame, and your doing normal water changes to bring them down, it will, but not for a long time.

I actually think a 20g water change weekly is more than enough until you see the levels come down. But if you're not getting to the source of the problem you'll keep on having the same results. Nitrates should be pretty low in most tanks unless they are overfed or heavily stocked in that case a skimmer is a most have especially if you're carbon dosing.
