ok, i think i read a lot of things wrong. here goes again. on the right meter, it reads 1000psi for the tank. on the left, it reads a little under 20 psi. Are these correct settings? I am trying to open my needle valve, but no bubbles are coming out in the bubble counter.
I am not sure how many bubbles I should be allowing. The previous owner told me 1 bubble per 3 seconds. Is this about correct? Those who have a 60 gallon, what do you bubble? I only have a few sps growing now.
