Hannah phosphate or phosphorous checker?

[Tuan’s Reef]

looking for a accurate and easy to read phosphate checker . BRS recommends the phosphorus checker but Hannah just came out with the ultra low range phosphate checker . Would you guys still go for the phosphorus checker since it can read a broader range?

Get the new one. It’s supposed to be as accurate as the ULr phosphorus just automatically converts readings to ppm. It also
Doesn’t shut down while you’re mixing the powder which I hated about the old one.

Wow! I’d upgrade just to avoid the shutdown. It’s always a delicate balance to get all of the reagent dissolved in the allowed time. Plus I’m getting pretty broad ranging results with back to back tests.

Went ahead and got the ultra low range phosphate checker.

Thanks! Might pick up the phosphorus checker in the future . Hope I don’t have to and the phosphate checker do it’s job.

I think the ULR is a phosphorus checker, not phosphate. Then you use the chart above to conver phosphorus ppb to phosphates ppm.

If it shuts down do you have to restart the whole process?

Yes.

But if you focused on doing your test, there is plenty of time

These 2 checkers are the same ?

 

[Deiblerj]

Ah means I did my test wrong haha! Dang it!

 

[mta_morrow]

They are different

I will have to make a video. There is never a reason for a shut down.

Mix for two minutes and hold the button for the 3 minute count down. The reagent is in excess and any undissolved (not that I've ever had a problem with that) will settle out of the photometer view during the 3 min count down.

The ULR Phosphate version does the conversion for you. Not a big deal to me as I record my results in my Apex log and it automatically makes the conversion from ppb. They are different and use different reagents, unlike the alkalinity units where the ppm and dKh units use the same reagent.
