bringin ph down?

whats the best way to bring ph down?

im at 8.52-8.54 lab grade ph probe on a neptune controller.

i do NOT run co2 and i do small bi-weekly water changes with ro dual di water and kent reef salt.

ive heard soda water, but i worry that it will have something in it to create a huge bacteria bloom.

ive heard rumors injecting fresh air into the tank via a air pump a couple times a day for short durations will help,but not sure.

any ideas?

thanks.

the way i have brought my ph down is with water changes

Most have problems with lower pH due to higher concentrations of CO2. It's difficult to understand why your pH would be that high without some type of dosing/additions/Kalk. Sorry to ask the obvious, but is your pH probe calibrated?

It depends on the CO2 level in the room the tank is in. Most homes have higher levels of CO2 because of the respiration of the people living in the house as well as the fact that many homes are quite well sealed up for energy savings. If you put an airstone in the tank you are in essence creating an equilibrium in your tank with your room. If it's already in balance adding air should make no diff. It's a pretty low risk first step to try. Also, the soda water might be a next step but go slow and observe the changes over days not hours. I'd also like to see you have more than one ph probe to verify it is indeed reading correctly.

as i said, bi weekly water changes is what i currently do. so that will be of no help.

it has been, i also have 2 other tanks in the same room and tested thier water, they were both right around 8.32, so still a tad high, but not as high.

I was thinking the same. Ive had the same issue and it was always caused by equipment failure. As long as it doesn't go any higher I wouldn't sweat it too much.

i have the window in the room open probably about 15 hrs. a day and my tank is completely open top and no hood.

it just makes me nervous adding soda water, to my tank.

i do not have another probe.

Are you using Kalk?

Are you using Kalk?

nope, i dont dose anything since i do such frequent water changes and really only house lps, my levels stay pretty decent.
