to sps keeper , what do you use to measure the po4?

[chercm]

anyone can advice ?

i having issue in determining the po4 using the hi736

I use the Hanna ulr checker, works like a charm , I'm impressed with compaired to their Calcuim checker

i kept having issues in trying to get the stable accurate reading , how did you do it ?

Red Sea works well for me.

I also use the Hanna ULR Phosphorus meter. I get VERY consistent results with it. I tested my Hanna ULR Phosphorus checker with the D&D Kit, and the results agreed bang on.

Here is a thread I posted a while ago, myself and Andrew discuss our exact method of using the Hanna Checker:

Have a look at post numbers 9 and 11 specifically.

I agree that the Hanna checker is the best bet ( for now) but Beananmials review on his website is dead on. You have to race the clock for no apparent reason, the results are displayed for a preposterous ten seconds( you better not get up to grab something from the fridge), and the sachets the reagent comes in are glued paper so you have to basically entirely separate the two ply packet to locate every remaining grain of testing powder. It works, and the testing is accurate but Hanna blew it in many aspects of this test.

Red Sea Pro, but I regularly cross-check with the Hanna ULR Phosphorus checker.

I don't have those same timing issues with my Hanna ULR checker. I do make sure I mix the reagent for no more than 2 minutes, but I have gone over 2:15 many times without timing out. And the results are displayed for over a minute. Maybe I got lucky with my checker.

Hanna HI713 checker.

 

[chercm]

is Red sea consistent on the reading ?

 

[Dexters Reef]

Salifert, but my levels are too low for it to detect, even when using it at double sensitivity. I wouldn't recommend it for low level phosphate detection that a SPS tank needs.

 

[chercm]

anyone tried to use the D-D phosphate test kit ?

i think u are referring to this :http://www.beananimal.com/other/hanna-hi-736-checker-hc-opinion.aspx

 

[Confuse]

Does anyone know if there's a difference between the Phosphate reagent and the Phosphorus one? I was told they were interchangeable.

 

[deepseadan]

I've tried them all and never been impressed with the consistency of any of them. I just go by algae growth on the back wall of the tank.

That may have been before, and probably still apply to the Hanna Phosphate Checker, but I can confirm that my Hanna ULR Phosphorus checker, has the longer time set.

My final result appears for longer than 10 seconds. In fact I timed it yesterday and the result was displayed for more than 1.5 minutes. I bought the unit a year ago in the UK.

Some people may have the older units with the shorter times set into the unit.

So, to sum up, I do not run against the clock, rather, my newer unit has very sufficient.

Milwaukee Martini low PO4 colorimeter. Works like Hanna full size colorimeter.
