My nitrate is at 80ppm what should it be at and how do I lower it ?
My guess is to lower it you do a water change but please let me know thanks in advance

I'm still new here (although I've kept fish for years), but....I'd do a water change, and *keep up* on your water changes (and with rays I'd do them even more often!). You could add some plants (floating even) to help absorb the nitrates, and you can add nitrate pillows to your filtration to help, too, but I'm not a huge fan of those. If you keep up on your water changes and have sufficient filtration, it should eliminate the 'need' for anything like that anyway. Just make sure you have enough biological filtration to keep up with your ray's bioload.

Good luck!
 
Waterchanges above, and I use carbon. Try some floating plants since you have rays you can add some bog or lily's, maybe even pond plants. Pond plants look awesome in tanks as half of it is in the tank and the leaves come out of the tank. If you don't want it in your tank you can put it in the sump if you have one.

The most effective way in my opinion is to add a drip system. It cost me around $100 per tank to add one but it has done wonders for my nitrates. I use to have 60-80 ppm all the time even with 3 time a week water changes. With the drip they stay at 10 ppm which is what my city water is.
 
So what is the safe level for rays when it comes to nitrate level ?? and I don't want plants not a fan of them but I do have carbon in my filter also I'm going to start daily water changes

Yes as mentioned above water changes and plants will lower your nitrates down. U can also try seachem purigen as it also helps reduce nitrates. I'm using 1L of it on my 450g and it helped reduce my nitrates down to 30ppm after 1 full weeks of feeding before end of week water change. After water change my nitrates drop back down to 5-10ppm. Without the purigen my nitrate levels use to raise to about 60ppm by end of week. Also my 450g is heavily stocked with large monsters.

I would personally shoot for 40 ppm or less. High nitrates has been suspect for a lot of ailments rays suffer including mystery death and loss of appetite
 
In my old tank which was heavy stocked my nitrates were 80-100ppm with no problems and the rays bred in that

I don't think nitrates have a big impact on rays but it's best to do 2 x 25% water changes per week not to just lower nitrates but to freshen up the water

A drip is perfect
