Im not a biggie on anything but API test kits but I am lowering the pH in my 29g tank with peat in the filter and I want to keep a close eye and do multiple ph's in a day to see when to add more, etc.
How accurate are they?
Thanks

I guess it measured about the same as the API, but the orange was hard to read, and it started fading (in my godawful overstocked-as-per-bad-advice ammonia-soaked tank I called cell-block #3) in about 10 days. If you need a tight read, from my experience, I'd skip it. If you need a panic alert to tell you you've dropped from 7.8 to 6.5, and only need that for a couple of weeks, then I'd say it'd be worth it just because it's such a quick glance.

Who knows, I may have gotten a stale one, or my tank was uninhabitable even by a test strip. At this point, though, I'd say the pH Alert isn't even in the same practical product line as the Ammo Alert, which I love.

I bought two. Now you've given me a reason to try the second. I'll update after a week or two if the need is still there.

Thanks, the ph alert and the api are running together right now. The ph has only dropped a little since I started, I am going to give it a couple days and add more peat. Ofr coarse I am going to put some mopani wood in as well.

I was lucky enough to have a digital Ph meter - from my other hobby - winemaking - so I can get unlimited readings anytime continuously.
This is SSSOOO much better than those titration/color tests. I wish they had them for ammonia/nitrate/nitrite etc for the color challenged among us. I struggle mightily with "slightly yellow to very slightly yellow"
I think these cost around $100 - but consider how much a few years of test kits cost and that you can get readings instantly several time a day
Some of the best money spent on the aquarium.
