SeachemPh Alert for Freshwater

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.

good,helps me keep my fish tank clean

The control color in the center never changed colors after 3 days in my tank. It stayed at 5.8. I already had an API test kit, but I thought this device might cut down on the times I had to use the test kit. After the Seachem pH Alert seemed to not be working, I bought a digital meter to verify. My pH measured around 6.6+ with the API kit (sometimes hard to get an exact reading) and 6.88 with the digital tester. If I had not been given a refund, I would say I wasted my money.

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

It took a day, but finally calibrated.

I thought with it being a brand name like Seachem it would be accurate but when I checked it against my chemical ph test kit it reads between half and 3/4 of a point low

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!

Funcionó excelente

Non chiara la colorazione che assume per indicare il livello di ph

Got this for my marine aquarium to monitor the aquarium works brilliant last a while so no need to change very often keeps you aware of what's going on in the aquarium

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.

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.
