Need help with Nitrates

I have a 12 gallon tank fully planted and loosing fish. I have not been testing the water or doing water changes for quite some time. I’m using pressurized CO2 and dosing PPS pro as per the instructions from the manufacture. At first I thought I was gassing them and my drop CHECKER just wasn’t working so I turned the CO2 completely off. Came home from work today and found another dead fish so I decided to check my water and found everything perfect but nitrates extremely high. Can this be the Ferts that I’m dozing? I have another tank that I dose the same solution with and the parameters are Good. See pictures attached. I could really use some advice thank you guys and gals.
One more thing: I have four or five Amano shrimp that will not seem to come out of hiding since I started adding fish. They used to run the tank now they only hide.Could that be a sign of something wrong as well? The fish I’ve lost are neon tetra’s and zebra Danio’s. I’ve also lost a handful of Ottos but I think that’s just because they like to die. ;) Plant Water Vertebrate Botany Green

1. Nitrates up to 80 ppm in a planted tank is the least of your wories. BUT Nitrates are relatively easy to test and raising or consistently high Nitrates is one indicator that other compounds are also accumulating.

2. You can certainly keep a planted tank that needs very little maintenance, including water changes. BUT can does not mean you should. Low maintenance tanks are specialty tanks that need to be designed with a forethought: specific choice of plants and fish, substrate, lighting, circulation. You do not see many of them running because a) not easy to set up correctly for the long term b) most people don't find them attractive.

3. Once your tank parameters start deviating too far from the local norm, introducing new fish becomes harder and riskier. Ever flew from, say, N. Dakota to Hawaii in winter? Then you can relate how the new fish feels. Some make it, most dont. Drastic differences in temperature, co2 / o2 levels, TDS, chemical concentrations, etc. are like multiple blows, all at once.

In short, start your water changes and keep them on a relatively consistent basis, as per posts above. Planted tanks present multiple challanges - no need to make your life interesting by skipping a basic step.
