🐟 Stay ahead of the curve with Seachem pH Alert—because your fish deserve the best!
The Seachem pH Alert is a compact, continuous pH monitoring device designed specifically for freshwater aquariums. Utilizing advanced sensor technology, it visually signals pH levels through a simple color change—yellow (pH ~5.4), orange (pH ~6.4), and red (pH 7.4-8.0)—eliminating the need for manual testing strips or kits. Lightweight and easy to place in tanks or filters, it offers aquarium enthusiasts a reliable, low-maintenance way to maintain optimal water conditions and ensure aquatic health.

Peace of mind.
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.

This is useless.
This product does not work only shows a beige colour that is not one of the colours on disc even though testing with liquid testers and electronic calibrated testers show water to be exactly 7 pH which should show as orange on disc not beige. This is second one bought as thought first one was just a faulty card but results exactly the same. Useless!

Not bad
Could be more reliable the colours often don't match on the dial and so it can be difficult to recognise the conditions of the fish tank.

easy to use and seems very accuarte in measuring the PH in our tropical tank. better than test strips etc

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

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
