Salifert vs Hanna
So I started a 28g saltwater nano in late March. I’ve been testing my water weekly and everything is stable but slowly working on better levels in calcium, magnesium alkalinity and phosphate. I solely was using salifert as my testing kit until this week.
Every week my phosphate has read zero.
I mean, I have the skimmer off. I have sun coral so I’m feeding with reefroids every night and overfeeding to increase my phosphate.
Yet, this week is still 0.
In anticipation of the reading I ordered a Hanna testing kit for phosphate because I can’t believe it’s still at zero after all this time.
First Hanna reading was 0.25 (eek)
Second Hanna reading was 0.35 (eek even worse)
Turned the skimmer on and went to Aquarium Arts their Hanna read 0.79 ()
Around 8pm checked with Hanna again after checking expiration dates (nothing expired) and it read 0.16.
Wondering if anyone else has had experience with phosphate not showing at all with salifert?
