Salifert has them on the outside of the box. :)

Are you winning?

So cannot confirm for sure but looks like I have bad test kits, calcium is low for sure but KH looks like to high now. Old API and RedSea both show low but Aquascape KH show 15-16.
Called RedSea for explanations, nothing so far but expecting a new reef pro test kit from them.

I've never heard of Aquascape test kits. Why don't you just buy some Salifert kits? They're easy to find, reliable, do lots of tests, have expiry dates on the outside, and affordable. :D I use a variety of different brands, but sometimes I wonder why when the Salifert does the trick. :lol:

:) some people work 6 day a week from 7-7, today is my day's off and my wife birthday so might not have time to go anywhere near LFS

Got new Salifer KH, new reading 12.8
And Nutrafin CA 300
AI had no Salifer CA test

Oh, these were old test kits you had laying around? I thought you went out and bought this Aquascape kit.

Well that's annoying. I hate driving to LFS to pick up some supplies and they're out of stock. Is the Nutrafin a new kit?

Yes both kit new and have many years left. Nop the AquaScape I picked up from someone.
I noticed the new Salifer have 2020 expiration date, how long the RedSea was sitting in the store if expires in October 2016!

Slowly my CA start to get up again, 410 was this morning, for the last 4 days I was dosing 50ml AK only and 200ml CA, KH still up at 12.
As for the RedSea test I'm very disappointed, called and emailed them with little to no response, one of the lady she said she will talk to her chemist and will see if they can provide a replacement or not! Wtf I paid $80 for that stupid test just back in May or June

Update-
Received replacement from ReSea it's about 20-30ppm different from Salifer.
Got from a friend a Seachem 425ppm reference solution, unfortunately it's 2 year old and both RedSea and Salifer read way to high value, near 520-550ppm
Is there any safe/sure way to home brewed calcium test solution?
