The more you talk to these "experts" at these stores the easier it will be for you to call B.S. And really, if theres any questions you have just ask. Everyone loves to help.
Do you have a test kit? The
LFS prob uses strips and recommended them too I bet... lol If you don't already have your test kits you'll def need them and you should get the ones with the little test tubes. Far more accurate than strips.
I learned all this the hard way.
Nice chatting with you. I get so bored sometimes and I just love my fish.
