Asking about EI again ? ;)
Do you think its too much if i dose 9 ppm KNO3 and 1.2 ppm KH2PO4 each other day , 3 times per week ?

Till now i don't see any change, but it's maybe too soon to talk about this , i changed the ferts about 2 weeks ago .
If co2 is in good shape i shouldn't see any change because of the ferts

Got a question for the more experienced of you guys.
Considering co2 is in good shape, ferts and lights are ok , plants are growing ok without algae (so basically this is a perfect scenario) .
After starting the light in how much time should plants start to pearl ?

Thanks

If your light is high enough (let's say 50-60 PAR minimum) you should start seeing plants streaming O2 in 5 minutes. Pearling is something that occurs with O2 saturation, and that depends by many factors (flow, current, Co2 diffusion, etc). In my 75 streaming starts in 5 minutes with 50-60 PAR at the substrate and pearling is visible at the end of the day. In my new 20 gl with Co2 with same PAR but more current and less Co2 diffusion (more Co2 bubbles around), pearling occurs much sooner... But still, hard to understand if that "pearling" is due to Co2 trapped in the leaves or plants actually trapping their own O2.

I'm talking about Co2 trapped in the leaves , see picture attached , of course at the beginning of the photoperiod these bubbles are smaller than in the picture (this picture is from google , not my tank)
Thanks

Thanks skins. Excuse me if my questions have been answered previously, I am just trying to get a firm grip on the whole picture. Do you think the original problem was because you co2 injection was inefficient with a po4 deficiency? Or just a co2 injection issue?

Thanks!

Yes , all the issues were related to co2 , was insufficient , since i switched to cerges reactor all fine
