Is the Hanna Phosphate Checker worth $50?
How many tests can you make with it? Can you buy replacement reagents?
It's either Hanna or Red Sea. Any thoughts?

hanna phospahte in my opinion is not worth any money but hanna low range phosphurus is. it comes with 6 tests but u can buy refills of 25 tests for a cheap price of 8-12 dollars.

He's referring to the ULR Phosphorus Checker, which is in theory a bit more accurate than the Phosphate Checker, for about the same price.

^In theory? What is my best bet in your opinion?

I'd try the ULR Phosphorus Checker, but my tanks always were low in measured phosphate. I think for most tanks, the ULR is appropriate, though.

Who makes the URL test?
Any links?

The ULR is a Hanna product.

hanna checker makes both phosphate and UL phosphorus both for $50.
here is a link. https://hannachecker.com/index.php?p...mart&Itemid=29 to me this is a lot more precise and goes in lower range than a regular phosphate test. they both come with the meter and 6 tests. u can buy test in lots of 25 for less than $10.

I've been using a hanah colorimeter 713 for abut 5 years. It's the full sized model ,pruchased before the checkers were out. It' reliable and consistent. I'd expect similar performance from either of the
hananh PO4 checkers . They get generally good reviews. If I were getting new device I'd opt for the ULR model.

I use the new Red Sea kits for some of my tests, but for PO4, you really need a good meter, and the Hanna checker is a good choice.

The Hanna checker is the best currently available. Measurements are +/- 0.04ppm. My experience/data suggest an even tighter range. Hanna makes a good alk checker also. Be sure to carefully add all the powdered reagent to the 10ml vial for reliable data.

I don't know what I would need: high or low phosphate. Or ultra low range phosphorous?

IMO no point in testing PO4... if ya got algae...ya got too much phosphate...no algae...no problem...at least in my experience.

Well there is two huge blobs of turf algae both on the same small rock. Instead of removing the algae or throwing away the rock, I'll just put the rock in my cpr aquafuge. It should help me with the eternal battle of the micro algae on the glass by growing and stealing excess nutrients from the micro slime. Also if I cut back on feeding frozen, it should help. Oh, then there is water changes.
I'll put buying the test kit on the back burner for now.

I sold my Hanna Checker and have been using the Red Sea Algae Management test kit. For the same money you get both PO4 and NO3. The Red Sea accuracy is much better.
I would do repeated tests with the Hanna Checker and get a different result every time, mostly 0.00. My actual PO4 level was .02, but the precision of the Checker is not precise enough to measure at extremely low levels. |

How do you know that the level is 0.02 ppm? I agree that the Hanna Checker has a significant error in that range, about 0.03 ppm at least.

Do people with established tanks to regular p04 testing? I find since the tank has found it's groove and I stick to my routine I have no problems. Watching the algae film on the glass seems to be a good indicator for any rising nutrient levels that may trigger a test.

I run GFO and the PO4 Checker has helped me watch things so I have a guide as to when to switch it out. It can vary and that saves me money. I got in early on the Checker about 5 years ago and only paid 39.95. I've only bought reagent three times and on-line its about 10 dollars. Its accurate enough for my purposes.

I like my checker, but like others have stated, it seems to have a 0.03ppm uncertainty on the low end. Mine bounces around between 0.00 and 0.03ppm when I test. But to be honest, that's fine with me. Most people recommend a phosphate level below 0.03ppm from what I've read anyway, so the deviation doesn't matter.
My checker was reading 0.00ppm and I had a guy at work run my water on the ICP. The ICP came up with 0.005ppm. |
