I can feel past rage rising inside of me as I read that. Oh how I hate that.

I don't really press hard at all though on my elos bottles. It's almost like a gravity drip with a tiny but constant amount of help. My tests for ca, alk and mg may be wrong but they are always consistent. Whatever my 'real' levels are...they are surely consistent which I think is half the battle.

and another reason I don't like the drop count type.

how's the colour change though? Is it one colour to another, or change in shade of the same colour.

i like the elos kits i get consistant results
i only use elos for kh mg and ca tho
the color change is definately noticeable

ca goes pink to purple
mg has 2 tests red to green and pink to purple
and kh is blue to yellow

Hey Mark, if you are still a fan of the Salifert test kits we sell them here at Progressive Reef-and we are pretty quick with shipping in stock items such as the Salifert Test kits. We carry the whole line.
Cheers Ronnie

Why not go hanna colorimeters/checkers? We really like ours the ease of use and the accuracy and it is the cost of a elos test kit.

If you're asking about the seachem reef status tests, it's an unmistakeable change. I'm on my second Mg/alk test kit and I've noticed the indicator on the second one isn't as dark as the first, but I've been doing two drops instead of one and I luckily have some left from the first kit. The alk test is the difference between a sky blue and pale, almost colourless yellow, with a fairly dramatic colour change at the end point.

The MG test starts out a dark fuschia and turns dark purple at end point, and the calcium goes from a rose pink to a really pretty blue.

Because you dispense such tiny volumes of reagent with every drop, it's possible to get right up to the end point and not be sure if you've gone over, but in that case you just read the volume on the syringe before you add your second drop.

How do you like your hanna colorimeter? I was thinking about purchasing one soon as my Elos KH ran out.

Its great put water in the vile calibrate it then remove the vile and add a few drops and place it back it and bang you have an exact level. Its very precise i just cant wait till the calcium and mag ones come out.

FYI
 

I am having issues with the Salifert Mg test kit, the readings are a lot higher compared to Elos. Actually are a lot of other people are having the same issues as you can see by the post on RC http://www.reefcentral.com/forums/sh....php?t=1986944
I'm waiting for a response to this matter from the Canadian wholesaler of Salifert. In regards to Elos I hate counting the drops.


Ditto

I am not sure I agree with the others about how ELOS is inaccurate... During my time of SPS issues, I had taken water samples to my LFS, as I thought maybe my kits or refract are out of whack. My LFS uses Salifert and API, and when they tested, the results were accurate to what I got using exclusively ELOS.

In saying this, I use ELOS without any complaints... I have also just tried API and Salifert for some things, and they seem fine also.
