Diffusor means alot of surface agitation

I have some surface agitation in my 180g. I am using AM1000 CO2 reactor. My guesstimate is that the agitation is just enough without too much of CO2 degassing.

I have read that plants seems to prefer those small bubbles that are produced by diffusor. Am I correct to say that, in a tank that uses diffusor (or Mazzei), degassing of CO2 thru surface agitation DOES NOT occur since CO2 is not in aqueous form, but instead in tiny bubble form ?

If my assumption is correct, would it be safe then to have plenty of surface agitation in such tanks?

 

Thank you Hoppy.

I wish I have the opportunity to look at his tanks . Anyway now I am more encourage to have more surface agitation.

Actually my AM1000 is run by Eheim 2228 but I noticed that the flow into the reactor is too weak to power it. So I have stopped using it and decided to use a diffusor, just a tad smaller than the Rhinox 5000. And I do not hesitate at all after knowing that Tom too is switching to diffusor on his 180g http://www.barrreport.com/co2-aquatic-plant-fertilization/5311-co2-mazzei-vs-diffuser-disc-what-important-factors.html .

However, in this thread http://www.barrreport.com/co2-aquatic-plant-fertilization/5361-aqua-medic-1000-120-gal-rhinox-5000-a.html , Tom recommended to have 2x diffusor for a 120g. I am only using one as my SunSun wavemaker (like Koralia 4) at 5000L blows those tiny bubbles to every corner of the tank.

I have more than 7bps. I add 3tsp KNO3 and 1tsp KH2PO4 3x a week. Also 1/2 tsp CSM+B 3x a week. My setup is Iwagumi with HC and HG.
