Seachem Ph Alert, ContinuoUS Ph Measurement Device For Aquarium Water -Colour Indication

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

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.

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

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.
