The azoo comes with a factory set 80 PSI evidently, i was suprised at this. so i brought it down originally to 40 PSI with the solenoid off, so maybe that's why.
After 6 hours or so, the plants are pearling quite nicely. No stress signs from the fish, just as lively as usual. If anything, they are more lively. pH has dropped and is holding steady at 6.6 I've been testing every hour or so.
I'm not using a drop checker right now, but i'm keeping a very close eye on the pH and fish breathing etc. The bubble rate is still holding steady and the PSI of the output guage is still holding just above 30PSI after 3-4 hours.
EDIT: I think the pressure drop first happened just because I was messing around with the needle valve a bit, but not certain.
Another thing comes into play now though... Do you use dry ferts? and if you do, any particular place you get them
