Fishless Cycle Question

    Hi all. This is probably a basic question.....but when (if ever) do you do a water change when doing a fishless cycle? Only the ammonia gets super high?

    Short answer, no. Unless your ammonia (or nitrite) levels are getting crazy high during the process (5ppm - 6ppm), there's no need to do a water change. Doing a water change would more than likely slow down the process than help it. Just monitor your water parameters and let the bacteria do all the rest.

    Thanks very much. That's what I thought but just wanted to make sure
