Just ordered a new test kit but won’t arrive for a few days, what else could I do in the mean time incase they are actually that high?
I’ve got some tunnels and overhangs I’ve created with the rock and can’t get the siphon under there to clean the sand is there any good inverts that could clean under there or any other ways to reduce nitrate that’s effective? I’ve heard of using vodka but that seems dangerous to the fish?
