i cant get my pH up?

ive tryed opening my windows, adding borax/bakeing soda mix and all i can get it up to is 7.94 in the day and its about 7.75 at night. what else would you try ?,

 

What is your alkalinity at?

Increase your surface aggitation.

 

alk last checked about a week ago was at 3.6 but thats as high as my red sea test kit goes i need to get a different kit. and i will point more power heads up. thanks i will try that.

 

Have you double/triple check your test kit or pH probe? Recalibrate, try another calibration solution, try another test kit.

Try the aeration test, take a cup of water outside with an air stone for a while and test the water out there to see if maybe even opening the windows isn't getting rid of the excess CO2.

 

mine does the same darn thing.. Sometimes it goes up to 8.04 but usually hovers around 7.90. Its a pita, especially since my alk is at 13. I dont want to push it up higher..

 

sounds just like my tank, i will try the air stone thing and see if it helps.

 

already in 20 minutes sense i pointed my PHs up it went to 7.96 you may be right i need to shake the surface a lot more. thank you....

 

My surface takes a beating and still nothing. It only raises a little if I open my windows, open my hood and sump doors and blast a window fan at the sump. Only then will it go up to 8.10 but then again I live in the south and leaving the door open is just unheard of during these months. I need to try something else.. I even have an airstone and air pump for a 40 gallon sitting in my overflow to get even more oxygen. I wish there were a way to run an airstone from a pump outside my place to bring in fresh air.

I know its extreme and I wouldn't do this for financial reasons, but what about running a pure oxygen line from a pressurized tank? I bet that would kick butt!!

 

i wonder if we ran a air pump in the garage would that be enough? and now my pH is up to 7.97......

 

Don't stress too much about this. 7.94 during the day is still in the "o.k." range. Try using Sea-Lab No14Ph. It will balance the tank to 8.3. It is made to be used in conjuction with Sea-Lab Formula 28, but can be used alone. I use them in tandem and my Calcium stays at 480-500 ppm and PH at 8.2-8.3.
