I'll try and make this as short as possible while getting the most information out.
My nitrates are consistently high the last 2-3 months. 60-100 at some times.
Well water tap has a nitrate level of 5ppm.
I realize the results from test kits available to most of us should be taken with a grain of salt, but I've used multiple kits and had multiple shops verify my readings and we've all come up with the same numbers.
As i've noticed this I dialed back the ferts as to the point now where I'm dosing no KNO3 at all and still getting high levels in 1 weeks time.
All other parameters are the same as they've ever been.
The tank is pretty heavily planted and lightly stocked so I assume many of the nitrates should be getting used up.
Fish are periodically dying off. I had a large die off I blamed on getting unhealthy fish from a store, but now that I've read on Old Tank Syndrome I think I may be in that boat.
It's getting frustrating and I'm thinking of tearing the tank down and starting anew. Any help is greatly appreciated and I'll make sure to answer any additional questions you may have. Thanks. Kevin.
