High ph

Postby Gary on Wed Jan 03, 2018 3:10 pm

Hi guys looking for some help with a high pH problem I've been having for that last week 8.2 at night and goes up to 8.6 at the high point of the day. All water parameters are good I'm not dosing anything. Any help would be appreciated thanks.

I wouldn't worry about it. PH will be highest at the end of your lighting period and lowest right before the lights turn on - it is natural to have this swing because of photosynthesis.

But, if you are worried about it or think it is impacting your livestock, you could play with spreading out the lighting. Have the lights come on, turn off for a few hours in the middle of your lighting cycle, and then turn on again to finish the lighting period for how many hours you are trying to have the lights on.

What I used to do to minimize PH swing was have the refugium light/s on opposite of when the main tank lights were on.

Yes I do the same with the sump. I think I tracked it down to my alk. Is high and so is my Cal. Don't know why it's high I don't dose or have a calicum reactor. Just instant ocean reef Crystals.This is a 6 mo. Old set up with very little Coral as of now. I'm guessing that because I'm not using up ALK or Cal. And mag. I do water change every 2 weeks I'm getting a build up of all 3 making me have high pH. Does this sound rite or am I missing something please chime in :)

Interesting. I am doubtful it could be from the salt, unless you got a bad batch. The only salt I had wonky readings from was Oceanic - and then I would mix that with Reef Crystals to get the readings I wanted. Not sure what to tell ya. Any chance you could try a different batch of Reef Crystals?

What are you using to get your ph number? If it is a pro e has it be calibrated? I wouldn't trust most of the test kits to get an accurate measurement either.

I'm useing a pinpoint pH probe. And I re calibrated it when I seen the pH was high and no change so I calibrated a new backup one and still the same. I have been doing 30 gallon water change and I'd has been coming down got it to a high of 8.54. I also will do another water change tomorrow my new box of salt came in today
