Am i going to be ok with this?

[thatindonesianreefer]

Hi
So i accidently bought tye wrong hanna phosphate checker (lr instead of ulr) and i just wanted to know, will i be ok in the long run with it? My reef is about 2 years old.

It'll depend on your tank's measurable phosphate but you'll be better served by the ULR in the long run. :)

My tanks range is about 0.03-0.5(0.5 during a spike)

Then the ULR version would cover that range. :)

Yes i wanted to buy the ulr but accidently bought the low range so will i be ok?

You should be fine, that’s what I use, it just won’t be as accurate in the lower ranges ( +/-0.2 ppm for ULR and +/- 0.4 for the LR)

Another and new question is what are these readings as if my phos are really that high my whole tank should be filled with dead corals! Ive used up like two reagents

You're fine with the test kit you have.
FWIW .03 mg/l is the minimum threshold level to prevent phosphorus limitation in corals, identified by researchers at Southampton University in England using corals maintained in an aquarium for about a decade. .3 mg/l is what corals are subjected to with upwelling in the ocean. .5 mg/l might be acceptable for some as acros have been shown to increase growth up to this level. .9mg/l is the level the Steinhart Aqaurium's ex situ sexually reproduced acro colonies are being grwon out with. Rich Ross's (who's part of the team at Steinhart) has his acro dominate mixed reef sitting at 1.8 mg/l, his tank can be seen at the beginning of his MACNA presentation on phosphate. You can see his current levels as well as some cool videos of corals spawning in his thread.

So is my test kit inaccuarate?

If you tested it twice and got the same number, I would say you did the test correctly, the only way to know if it’s inaccurate is comparing test results with a different test kit.

If your corals are fine, I would not worry too much.

Ok thanks

So the first test it said “0.90” ppm and the second on read “0.83” ppm

If you use the mean of those two numbers it would be at 0.865 honestly if you aren’t keeping anything super sensitive like acros, I would not be too worried about that number, of course I would be trying to get it down a bit lower but I would not drive myself crazy over it.

Ok, yeah then I would just focus on doing a few water changes maybe to help lower it, a you should be good to go !

guy might not realize it…
but you doled out some excellent information.

You test kit is fine and is more than accurate enough. FWIW, any single test result from a given test kit should be taken with a grain of salt. There are a range of variables including daily fluctuations in parameters and fluctuations from one place to another in an aquarium and inaccuracies on the part of aquarists that can cause variation from one test to the next. If you want to vewrify a tester or test kit "standards" are available that will give a known result but it's easier to use multiple test kits to get an average. I've attached a comparison of test kits done by the Dallas reefer club a few years ago and you can see there's quite a bit of variable results using the same set of test kits.
