Question about Hanna P04 ULR

Hey guys, i searched for this and came up how to convert ppb to ppm or Phosphate,

Now my question is, when we calculate do we calculate 3.066 and when we get the answer we divide by 1000? im a bit confused here,

Example : 2x3.066= 6.132 P THEN do we 6.132/1000=.006132

OR

Example : 2x3.066 = 6.132 P for phosphate

And to get PPM, 2/1000= .002 FOR ppm

feel free to call me dumb!

 

ppbx3.066/1000

So for example 14(ppb)x3.066/1000 = 0.042924 (0.042ppm)

 

AH, so ok i got 2 PPB , so my PPM would be .006??? is that high? its for a SPS tank

 

.006 ppm is VERY LOW, I typically aim for 11-14 PPB.

 

thanks biocube, but atm im going through some NTS, tank is 2-3 months old. should i still feed my corals?

 

I would think so, your nutrient levels are very low. I would feed them and keep your levels stable.

 

Also another question, the cuvette when you add your tank water into. i notice that when you fill your water into the cuvette how do you go by? do you stop where the water level reaches the 10ml mark, or do you go by the middle when it reaches the 10ml mark,

am i crazy here or do you understand what im talking about

 

Ummmm you lost me, but I put water into the vial I fill it up to the white 10ml line.

 

found it! a friend helped me!

Nice!!
