When to be concerned about high PH?

[Dave & Monica]

Over the winter I upgraded my 150W (x2) to 250W (x2) lights

Caused Heat issue, so installed fans on the apex controller to keep temp down.

Noticed a higher ph; normally between 8.1-8.4.

Now it's spring, with higher temps out side, and house temp is between 68-72. But that means the fans blowing across the water in the display more often(also where ph probe is). Ph is now hitting as high as 8.57.

Problem is my alk is at 7 dkh, and normally I keep it between 8-9. I'm worried if I put more Randy's 2 part (recipe 2) then I'll further drive up the PH. It's been less than a month since I last calibrated the probe. Second link in the history has the blip where I can see when I calibrated it.

Should I be concerned? Recommendations please.

Does the tank have a skimmer? I'm surprised that the temperature can get that high without some limewater involved. I might check for surface films and clean and tune the skimmer.

I wouldn't worry yet, even if it is accurate, but it is pushing the optimal limits (IMO).

Jonathan - I definetely have a skimmer.

Randy, Thanks, I printed the article out and will read later this am. Apple says there's an app for that, you can say - there's an article for that.

Maybe I need an app that supplies articles.

I like that idea Randy! being stuck home with a broken ankle I have been reading your articles. In the past 2 days I have learned more about this hobby then I have in the past 3 years. Thanks for all your hard work and time you put into it!

You're welcome and thanks.

Good luck the the ankle.
