new Red sea Alk test kit ??

[cracker]

I just purchased a refill for a red sea pro alk test. They have changed the color of the solution & this requires a new color card. I however didn't get the card with the kit. The LFS owner says Red sea will gladly send me a card. I hope this is true. Anybody else have this problem? Thanks !


I understand this new kit goes from blue to a green end point. If YA get yellow You have gone too far. The LFS guy had a picture on his phone sent to him by red sea rep but I can't find it on the redsea site.?? Ok I'm t not that good at guessing!

If you have a pH meter, you can figure out the exact color yourself. The solution will hit pH about pH 4.2 at the endpoint. That is all the color is telling you anyway.

I usually wait until the blue just turns lime green.

They told me they didn't have the cards yet but it's been several months. Let us know if they have them in, I'd like one as well cause it just bugs me that mine doesn't match, haha

Thanks Oakie ! That helps a lot ! I certainly will let You know if they come thru with a card. I fail to understand why this left the factory with out the cards !

also thanks to cm !

Ok just did side by's with the new & old kits. new kit I "think" I got a 7.6 too low
old kit I got 7.3 7.4 way too low
I just have to get used to this new kit is all.

So I got a response from Red Sea. They will send me a card. Let's see if I actually get one.

I just purchased Red Sea Alk test and mine is still the old colors. Didn't realize over dosing was an issue. Interesting

Kind of the reason I went to a different test kit for my ALK

I use my RS Alk test to spot check my Hanna. They are usually pretty close.

I do the same with the Aquaforest. I found that the Hanna, ELOS, and Aquaforest were the closest to each other.

I loved my old kit with the darker colors this new one is hard to see the change. I will also try to get a card and ask if there is a way to darken them.

Ya I'm not getting the same results between the old & new kit ! I do them side by side they differ too much. Could be my eye also.

I find holding a white index card behind the tube makes it easier for me to detect the color change.

that's a lot of trouble to go through when using a "premium test kit"

agreed ! If I could just see where the new kit agrees with the old. it's yellow before it even gets close.

When I compared the new reagent vs the old they agreed, but I had new bottles of each. I emailed red sea about no card with new color, blah blah. They sent me a new bottle of the "old" reagent to compare kits
