Hi,
If chlorine is the only disinfectant used by your water authority, you can remove it by standing your water for a couple of days in a blue barrel...where the chlorine will simply flash off. If, however, they use chloramine (increasingly used almost everywhere), it's a bit more complicated. Use vitamin C tablets (google for the dose rate) and that will break the chlorine/ammonia bond and allow them to dissipate. Putting an air stone into the blue barrel will expedite the process. Set yourself up to capture rainwater to use in your top-ups and water replacement.
Cut back on the feeding while the high nitrite levels persist...and mitigate against nitrite toxicity by dosing the system (no more than half a cup) with pure (pool) salt which you'll get cheaply enough at your Lowes or Home Depot store. Boost your aeration.
