api reef master kit?

for calcium the true blue endpoint...

is it when it turns from pink to blue or when its deep deep blue?

Mine starts pink, then turns kinda purple, then within 1 or 2 drops after turning purple it turns blue. I count to the point where it first turns blue.

I always wonder this

It's supposed to turn pink/purple first, then blue. That's when you stop counting.

Personally though, I always had a hard time telling, so I switched test kits for Calcium. I now use Elos and the endpoint is much easier to read.

It turns pink then you stop when it ends up blue.

 

[ser_renely]

but there are lots of shades, that 1-2 drops change

I have no problem tbh when i do the test and it starts to change it is usally one or 2 drops till final color.This is close enough for me as long as it shows in the range i am looking for 380-450 then i am happy.I normally keep my calcium about 420.There are prob more accurate tests but for the price api works for me.

what is worse is that i am colorblind lol... even worse is taht there are 324534 shades of blue lol

The way I understood the API instructions is that you will eventually reach a point when the addition of a drop will begin to change the color from pink to a light purplish. But you must keep adding a drop(s) until it turns fully blue (the end point).

For me, it's usually one additional drop past the initial change-over to light purplish, to make it blue. (So I don't waste that last drop, I just mentally add it )

lol

 

[mindytoy]

yeah thats true, i just stop when it turns purplish blue from pink, and think oh its in between 420-460...

the first drop that changes it from pink usually changes it to purple. 99% the next drop is the end point. after that your just wasting solution.
