Just wanted to let you all know. Not sure if this is the appropriate forum, but I figured more people would see it here and be interested.

The Calcium checker is $30 as well.

Is the Calcium Checker any good?

 

[shifty51008]

I like the phosphate and alk checker but the calcium one was a pain and gave diff. Results from my salifert which i trust more

 

[Devaji108]

thanks for the heads up I just might get one.

Thanks.. already had the HI713.. I've been wanting this one :fun2:

 

[Ratpack]

This being a phosphorous checker, how does it compare to the phosphate checker?

 

[outssider]

this is the one you want if you don't have any yet. it's better than the 713 because it reads more precisely at low levels. it reads as high as 200ppb phosphorus which is .61 phosphate.
