0 nitrate can only be attained in a sw tank where the use of n-p bio pellets and a reactor is used. in normal fw tanks a reading of 10 nitrate is mostly what you get after the tank is cycled.test strips aren't very accurate.

This is not true. Some heavily planted tanks can achieve, and you definitely do not need any special reactors to do it in saltwater. If you are feeding properly, have no mechanical media, lots of live rock, and do your water changes you can achieve no detectable nitrate or phosphate.

Throw your test strips away, they are garbage. You can guess better than they would tell you. Buy a liquid nitrate test kit and find out what it really is.

Yes i wanted to have 4 corys but i didn't want to keep getting more and having them die.
This raises another issue. Are you putting water that has gone through the softener into the aquarium? If yes, do you know how the softener works? Some add various salts to soften, and this is as bad or even worse for some fish.

Any chance you can use water prior to it going through the softener, and if yes, do you know the GH and pH of this water?

What do you mean phosphate pellets?

ANY food introduces nitrate and phosphate.

Nutrient control is about nutrients in and nutrients out. There is an enture article on this exact subject in the link in my signature. Check it out. If you have any questions about it let me know.

Its not too hard to have zero nitrate in a heavily planted tank, the plants will soak it all up

My tank is only lightly planted and I get consistent 0 ppm readings. I haven't had a reading over 5 ppm in 3 months (using API Master Test Kit for freshwater).

As long as you don't overfeed the plants help soak up the Nitrates.

Some water softening units add salt to the water. This may be the problem.
I have hard water (but is well water from a spring underground) my cory has no problem with it. In fact they are supplying the local store with fry!!
I have sand substrate (which they like) and local Elodea plants and another broadleaf plant that now reaches the top of the 20 tall tank. Also have an intank filter.
