Also, they run tests several times a day, every day. Their reagents are fresh - and this is the bane of just about every test kit out there. We learn very early on, in bio lab, that reagents are critical - and they are generally made fresh, in a lab.

So, the reason why you will see Salifert so highly recommended, is that they produce a top quality test kit, and the reagents are designed specifically for shelf life. They don't last forever, but they will outlast the others, several times. Are they expensive? Heck yeah - about as much for ONE test as others charge for a "Professional Kit".

I look at it this way: Even if you have a small tank, you've spent $100s of dollars on the livestock. Aren't they worth it? I chased an Alkalinity problem a few years ago, and was testing with a pretty decent kit (not Salifert). I found out the kit was showing only 1/2 the actually alkalinity. The company replaced the reagents - but what the heck?

BTW, I worked in a LFS for 8 years. Just because they do something, doesn't necessarily mean it's right...

As for the OP - he's already used to me (I hope!). I think he knows we're trying to help. I TRIED to get him remove his livestock several days before his tank crashed.
No offense but I've been in a few labs myself. Have too say that reagents come from a limited number of manufactures for there specific apps. Where and how they get there is a whole new game.Please dont think that a 30 dollar test kit does not have the same reagent that a 10 dollar test kit does. ....kinda like RO/DI filters....theres only a few players out there...

Just my experience. Your milage may vary.
