PostSubject: power head with lots of air!!   Fri Oct 09, 2009 1:23 pm

Hi all, i've got a power head in my tank with the option of adding air to it, if i turn the air right up (as opposed to no air) will it change the PH??

If so how (raise or lower).

High mattmania, I can't say I've ever heard of O2 levels in the water adjusting or governing water PH levels- I always thought it was just better to have as much oxygen in the water as possible so my little air breathers are cranked all the way up .
cheers J

im with Kurosaki J. ..extra aeration wont alter ph but thougth id add note regarding oxygen as maybe of some use ..

regarding extra air ive been told ..Airstones/filter air outlets aggitate the surface of the water which increases the oxygen which can be pulled from the surface but it doesn't actually add any oxygen to the water ..

however too much oxygen in a tank will not benefit plants hence lots of brown or dead plants ..this is because you'll have more surface agitation, the water won't hold the CO2 as well...

plants produce oxygen during the day which builds up to forms tiny bubbles, when theyre big enough they float up. Different plants produce oxygen at different rates..so plants would be better for increasing oxygen in water for fish

tanks with cooler temps also have more oxygen as hotter temps use up more,but obviously temp depends on what fish you have.

i have a airstone in some of my tanks, some not as fast as others as i use a valve to correct amount of flow/aggitation ..but maybe a idea to adjust flow if considering plants ..or add more plants if worried about oxygen..kaz

Good post k.bod, and the your explanation makes really good sense cheers .
Makes me want to do a minor re-think how my tanks are running.

to sum it up adding more plants = more oxygen?

Adding plants won't hurt mate, even if only a few
