PH issue that I can’t figure out !

[Jhillreef]

Ok, so I can’t get my Ph over 8.00 I have apex and probe is calibrated. Tested with 2 other testers. I have a 180g tank run a Aquamax Skimmer. I run the line directly from the Venturi to outside the house. I also, run a CO2 scrubber! I can not get it over 8! I do have a house full. But so does other people that I know get over 8. I ran Kawwasser in Ato. It did nothing but make my Alk go over 10 and nothing for PH, anyone have any insight? This seems to be something that I just can’t wrap my head around.

Does your tank seem to be effected by this?

 

[Pistondog]

You said it, you have a house full (of co2). Can you open windows, even just to see if ph goes up?
Do you have corals or a refugium? Both raise ph by removing co2 during photosynthesis.

I mean, things aren’t growing I feel like. It just seems oddly low for all the things I’ve tried

I have corals and I do have a fuge. It’s too hot to open the windows: but when I did it did not have a effect

How new is your tank?

How new is your tank?

About a year old

I had similar and run a fan under the tank across sump and it increased .2
Also, depending on your alk level, raising the alkalinity can act as a stimulant to increase your ph level

I have the same issue, low ph no matter what I do. Opening windows does help but in Indiana you can’t trust the weather from minute to minute so I can not keep ph over 8 for more than a day.

What is your alkalinity? If your alkalinity is low you won’t be able to effectively raising your pH.

 

[Jhillreef]

It’s 9.5 Alk. Added a fan under there today about 6p hasn’t done anything yet

When I ran Kawk in Ato got almost 11! So I stopped. It never did anything for my PH like I hoped

Ink bird makes some co2 monitors, maybe get one to determine house co2 level.

 

[Jhillreef]

Yeah I was gonna buy one at Walmart. They got some kiddie ones… see what I’m at.

 

[Pistondog]

Make sure co2, not co which is more common.

 

[InactionJackson]

I thought I read somewhere that a good surface agitation helps in releasing Co2 levels?

 

[Pistondog]

That assumes lowish house co2 levels, otherwise you are adding co2 from ambient, which is A if not THE major cause of low ph in our tanks.

 

[Jhillreef]

Could it be something that’s not air related ? Like is something in tank causing low PH? Could it be the skimmer?

 

[Derrick0580]

That assumes lowish house co2 levels, otherwise you are adding co2 from ambient, which is A if not THE major cause of low ph in our tanks.

So is this saying high ambient co2 can be countered by removing surface agitation and relying on a skimmer to add o2 to the water?

if your tank seems fine then don’t chase numbers
