Hi guys,
Fisrt of all in my name and Angelo´s thanks for reply.
After all i have writen and said i made that with the co2.. Is on a level that i can´t push more.
Still, cause of the 9 KH and as i also told before the pH didn´t drop a 1 Ppm .
Angelo: It drops from 7.6 to 6.8.
But this doesn´t worry me at all brother, cause with this Kh i (we) wont have to much flutuation in the ph.
The drop is a lime green. Even with this Kh we can reach high levels of co2.
The problem is the time to get it there and how...
My conclusion after a good looking to the tank: Diffuser!
To get this Co2 level i really need to open the "mouth" of the valve cause my diffuser is a pretty good blahblahblahblah.. . and i can´t increase more flow to the tank cause i dont´want to see the plants doing the mambo dance inside. And yes the Outflow does move the water doing aeration also.
So Angelo: as regarding the Co2 and flow my opinion is the same i allready give to other friends of us.
If i don´t buy a very good difuser/reactor to really break the co2 i or we wont´t get there.Cause if you have large bubbles coming from your difuser you will have losses of co2 and hard time to dissolve it in the tank.
The more the bubbles are break inside the difuser the best. Like dust coming out is perfect, cause than yes the co2 is imediately dissolved and become as part integrated of the water, as soon as he comes out of the difuser, and few losses (almost zero) to the surface. As few losses to the surface of Co2 than you wont have to worry of geting high levels of flow at the surface creating more o2 to fight the co2 coming to the top.
As of course with Co2 being pretty well integrated as soon he comes out of the difuser, than is in the water itself. And then we wont need an amount of circulation. Just enough to see plants moving a little bit. Just a little bit.
I look at this otherwise:
The more big bubbles of co2 i have coming of the difuser, the more time i need to force them ciuculating in the botom so they can explode under before getting the surface. And as most people have this issue what they do?
More flow! To force them being in the bottom cause they need more time to explode/dissolve....
This is my opinion. And this is what i will change The Diffuser!. I allready bought 4 diffuser in the past year..(Aquagro + Gush + Aquaeden + Rhinoxx 5000) and none of them makes what i see in a ADA...
There we go to a certain lesson i allready have very well presented in my mind..... in this hobby trying to "Save money" is worst then spent imediately.. lesson learned. ADA on it´s way...
Many thanks to all and i will retrive you news.
