lights and Ph

[jamos5790]

So what's the desk with lights on and Ph up and lights off Ph down? I have a sump should I run them opposites? How long to run each?

Lights on, plants and algaes are using co2 and releasing o2. The o2 raises the pH. At night, reverse respiration occurs, plants and algaes take in o2 and release co2.

Some folks run opposite light cycles to attempt to keep a stable ph.

Ok I guess that sounds good.

Hehe, I kind of gave you a skimpy answer. Sorry! If you want further explanation, I can make that happen....

I run my lights 6 on 6 off 6 on 6 off.

Edit: I don't run the fuge light opposite, I run that for 10 on 14 off.

<p style="text-align:left">jeffy has a co2 scrubber that you can make cheaply that will help keep ph up all the time not just at night
