Daily phosphate test ?

[jmichaelh7]

Im running through my Hanna checker reagents like water. I switched to every other day.

What other test kit are you guys using that’s cost effective

Salifert if I need a quick check of an off reading from my hanna's. Otherwise I use hannas exclusively.

Salifert are nice and cheap, and reliable.

Salifert is also my go to after hanna. It sure is a pain with reagents sometimes. Is there a reason you were testing daily? I test phosphates about once a week for what it's worth

I test phosphate with my Hanna checker daily. I have a refugium, so it helps me monitor uptake

Unfortunately, there is no test kit that can replace the URL phosphate kit from hanna. Nothing else can measure the low range the hanna does.


EDIT:

But if you want to know your not just 0, any cheap titration kit will work. Use the cheap kit first, if it says 0, then use the hanna. If the cheap kit says anything but 0, your good, no need to break out the hanna.

I personally keep my PO4 in the 0.1 to 0.3 range, so the hanna is needed to measure those low ranges.

The only reason I would test phosphate that frequently is if I was dripping in lanthanum or using lots of GFO. Otherwise, every once in a while is plenty.

I agree that the Hanna ULR kits are the only useful tests that are available to us, unless you keep phosphate 10x or more higher than natural seawater.

I agree that daily phosphate testing seems unnecessary unless you are actively making changes each time that would impact phosphate.
