So you moved the tank – and filled in new water, – and moved the filter ?
Did you rinse the substrate ?
First of all, – maybe these conditioners are okay, I dont know them, but normally any kind of chemical is not good for paros. But doing a search on it, it does not seem to be that bad.
But the water then is not soft ? If you use tap water, its not soft, – and paros can live in that, but they will not thrive in it, and they will become more vulnarable to diseases. Its not ideal.
