Ph won’t increase

[nawt2tawl1221]

My ph has never been above 8.0 it’s been around 7.8. I finally got some ph increase Kent brand. I added two teaspoons and look at it today the PH dropped even more. What’s going on? I’m very concerned the fish might die. I know you should have ph level 8.0 or a little higher. Anybody have any issues like this.
I added a picture because I do have a decent amount of air bubbles from skimmer and I’m wondering if this contributes to it.

Do you have access to fresh air flow?
I would open a window and check the Ph 24 hours after said window has been open.

Does it swing at all during night time/lights off?

Do not dose PH increaser please, it’s a loosing battle and impacts parameters. Throw it away

Are you running a skimmer? Aim your power heads up for some surface agitation.

How are you testing your PH?

7.8 is considered to be fine even though on the lower end

This should help...

pH low. Should I try to raise it?

My pH is always on the low side and has been for several months. Should I try to raise it and if so, how? My tank: -57 gallon, mixed reef, moderate stocked with coral, smaller amount of live rock, 5 fish (tang and 4 chromis), 5 months old. -pH swings from 7.55 to 7.95. -recently calibrated pH...

I have my living room fan on. No air from the outside.

Some further explanation here might be helpful. Kent pH up is just a high-pH buffer / Alk supplement. Unbalanced dosing of supplements is generally not a great idea and the pH boost is likely temporary for reasons provided previously.

DO NOT continue to add the kent product. It will boost alkalinity too much and is not the best pH increasing alk supplement anyway.

While that may aid, slightly, in air exchange, it's just moving around inside air. The reason for opening a window is to allow fresh air in and let old air out. The air outside has (hopefully) more oxygen in it than the air in your house since the indoor air's oxygen levels get depleted as you any anything else living inside, use it up.

It's not oxygen. It's CO2 you are trying to reduce.

Dose kalk and run skimmer air intake to outside. Case closed

Its a common misconception but you are absolutely correct.
Oxygen levels stay rather consistant despite the amount of c02 present.
