Ca - Salifert says 270, Elos says 450

Tony, why not just take the water in and have it checked at the LFS? I'm sure you can find something less frustrating to spend your $30 on

test a new batch of water.....you should know close to what that would be...than go with the more accurate kit. My guess is that the salifert is messed.

Not to hijack but I am having the same issues with my Ammonia test kits. Three different brands and three different results. I even tested new pre-mixed SW from before I did a water change and had different results. WTF?

Under 300 seems really low. I think if that reading were accurate you'd see some issues showing up.

Personally I've never used an ammonia test kit. After the initial large cycle you should never see any. And if you are just starting up a tank.....look for nitrite (never even tested for that one) at zero and nitrate to plummet to a respectable level. Really just testing NO3 will tell you where a tank is at in terms of the initial cycle.

I'd believe the elos 450 like stated above because I see signs when my calcium drops to 380-390 under 300 I think you would see serious signs
