Does higher air intake from skimmer help increase pH?

[reefluvrr]

Have anyone noticed their pH increase from jumping up to a larger/oversized skimmer with larger air intake from their previous one?

Take for instance if I have a skimmer that has air intake of 198 gal/hr and turnover rate of up to 317 gal/hr and now I want to buy a bigger skimmer that has air intake 396 gal/hr and water turnover rate of 634 gal/hr. Should I see a higher level in pH?



Thanks for sharing your thoughts or experiences.

Not to get technical, but yes more air = higher ph . The same can be achieved by a small fan blowing at the surface of the water. All this has limits of course. Useing kalk can jack it up to . ( by removing co2 from the water . )

It might make your ph go down. What matters is how much CO2 is in your air. Using a CO2 scrubber or outside air source is the solution.
A simple test. Take some tank water, put it in a container and set it outside. Test the ph after several hours. If it went up your indoor air is high in CO2.

Great point! I actually am running a co2 scrubber through my skimmer.

I am trying to be a little greedy by trying to upgrade my skimmer while increasing pH.

I agree, can I use a kalk reactor to slowly feed recirculated tank water and not top off water? I don't have much evaporation in a closed lid tank.

More air does not necessarily mean higher pH .... depends on where the air is coming from as noted.

That is unknown to me. Usually kalk reactors use fresh water .
But you could do it and post your results.
