That kit is fine for new starters who need to make sure there's no ammonia/nitrite in the tank. But apart from pH it doesn't include testers for water parameters. It's a pity they don't include GH in the master set, but many of us can get that info from our water providers.

Plus, you only really need to test for that once.

It's just easier to keep fish suited to your source water parameters rather than have to adjust the new water at every water change.

I have a master kit... but use test strips for my daily / weekly tests... I do think it's nice to have more than one way to test, just to confirm results
