IMO only, I would just get an ammonia and nitrite test kit if you are starting to cycle a tank. If you are unsure of your pH I would get one of them also so you can make sure it's close to being the same as where the fish came from.wot i want to know is wot is important (kits)there are so many
i have treated my water with wardley water care condtioner oders slim and basic tank crap and filted for 3 days so far without fish
