Seachem Ph Alert for Freshwater

Lost some fish and I couldn’t figure out why till I got this. To top it off I don’t have to test the water with strips all the time. A simple visible always on indicator is exactly what I needed

This Ph monitor began working within 30m just as advertised. It's also congruent with my test strips, so I would trust it's accuracy, although it's no replacment for a master test kit with additives. Would buy again!

I use this with an api test for ph and when adding ph within 5 minute the ph alert changes colors and matches exactly with perhaps a slight difference of at least .5 if at all but I trust Seachem products all the way as someone with every test kit and cares deeply about the quality of my aquarium.

Useless! I needed all the help I could get when my house water went awry. I bought one of these for some extra help, but it would never change off a certain color that wasn't even on the chart. It took me a while to figure out my pH wasn't extremely acidic, but rather had a faulty tester. I'm sure my fish appreciated that too! In one of the other poor reviews, where it didn't change off a certain color and he called in for help, that was the same color mine stayed on as well. No matter what fish tank I put it in, it never changed. I purposely tested it in very low acidic water and again with very high pH, and it never changed color. Very disappointed! And since I threw away the package thinking this company wouldn't have faulty stuff, I could no longer return it.

It took a day, but finally calibrated.

good,helps me keep my fish tank clean

Works great! Had a proper reading within minutes. Verified with chemical test to provide its initial accuracy and it was dead on. Will keep in all my tanks!

It's Ok but is't precise at all...It gives wrong parameters ...

Apesar de ser mais barato que em lojas físicas, vale mais a pena fazer os testes manuais msm. Coloquei o produto conforme descrito na embalagem. Além das cores não serem bem distintas, aparentemente mudou de cor apenas na primeira vez, mesmo eu tendo corrigido o pH algumas vezes.

Me ha gustado el producto, el problema es que solo pedí uno y me han enviado 2 con un mes de diferencia sin mi consentimiento y para colmo, me está intentando enviar un tercero. No envíen más por favor, cancelen lo que sea que será un error, no quiero uno al mes.

How to read it was a bit vague on the instructions, then realised it's the centre circle that changes colour & not the outside! Der! But does what it says & stops me having to constantly check PH... excellent product.

I thought this was a great idea and would save some work. But the colour in the central indicator never matched any of the colours surrounding it. This made it confusing and quite difficult to read. I even had others try to read it for me with the same result. Back to the test liquid now.

Its good when we have real time ph reading. Reading is almost accurate. Highly recommended
