I have had my ULR kick back readings that I could not believe. Unfortunately the only way to validate is other test kits/other reagent batches...or of course there is always the talking corals that can tell you! Seriously I have my doubts on the ULR Example get a reading of something abnormally high, test again immediately and see if it changes.... It probably will. With phosphorous I wonder how particular the two minute mix time is. Again perhaps best for the chemistry forum. Either way as testing goes it is human nature to test until you see a result you like then stop there In Which case Mankind can be a bad reagent. Call Hanna ... The more the hear from hobbyists the better. I also question the eBay/Amazon sale of reagents if it is not from Hanna directlyHow can I find out if my po4 and phosphorus are good ?
My Red Sea does the same Orange color. I swear the first bottle of Red Sea went to the Pink final color but now I don't know if this other bottle is good or not. Going to go buy a salifert today.Thanks for the help! Well my red sea test is no help either. It produces the orange color. Lol.
To the OP, just curious where did you get the link?
So salifert is pretty precise and accurate for alk also?

If you haven't been checking your Reagent before you use it to make sure it's good do it now. Both of mine were bad. So I have been accurately correcting my tank to bad readings from my Alk Reagent.

Guess I need to break out my Red Sea Test.
Haha true true!!Yes without the also
That link looks suspicious going to a wofoodotcom form page that anyone could make. Why it is not linked directly to hannainst?
