Dont do a water change on your big tank. Its a fishless cycle and doesn't need one. Id worry about your 46g for now. Definitely do a water change on that if nitrates arw high. Im guess you can say halfway. It could sit on nitrites for awhile before seeing nitrates
Yeah I'm doing a water change on that tank. I need to. Well at least you got something
