Hanna phosphate checker

Undertaker · Mar 29, 2019

I currently have the Hanna low range phosphate checker. Thinking about going with the ulr checker, do to the fact that I’m only running 5tbs of gfo in my reactor and still getting 0 reading. What are you guys option on the two, and do you think it’s worth spending another $50 on another checker?

I thank They are worth it My Hanna ULR (which I managed to break )found small amounts when the regular read zero. I have another on the way .

I wound up buying the ULR and selling off the higher range checker. Always reading zero was okay until i was chasing Dino's and needed a reading. Worth it IMO.

I started with the ULR cause I figured it would be the only one I would ever need.

No going back now!

Lucky you! I bought the High Range and they released the ULR like 3 days later

I don't have the ULR and I don't think I'd spend the money unless mine broke. Ocean water around reefs have around .1ppm of phosphate and my tank stays around .05ppm. I personally don't find worth in being able to read Ultra low levels of phosphate but if you really want to measure between .01 and 0 then it is what you will need

I could be way off base here, but, while I have heard good things about the ULR, I think the accuracy is still just plus or minus .02, where the standard low range is plus or minus .04.

Edit: Nevermind! It's +- 5ppb, or 5% of the reading. Not sure where I got that. Sorry!

Edit AGAIN: LOL I'm so confused. The HI774, which reads in PPM, is .02 accuracy. The PPB reader is the HI736. If I'm reading the conversion of phosphorus to phosphate right, that one is pretty similar, though, with an accuracy of .015. Slightly better.

Yes I’m talking about type phosphate not phosphorus.

Thx for all the input. Phosphate ulr it is.

Was just gonna say hanna released a ulr phosphate checker sometime late last year, but looks like you know that! I have the ulr phosphorous checker and love it, but plan to buy the ulr phosphate just because we are used to reading it in ppm and it does that for us.
