Your pump is fine. It never hurts to have more air but I can tell you that your pump is fine. How can you tell from a picture? Go take a picture of your bubbles and I bet that it looks like theres more than there are.

Instead of stressing out about your bubbles..you need to focus on your res. temps. Keep them at 68F for the optimal growth temp. The thing w/ Dissolved O2 is that the lower the temp..the higher it gets. The range you wanna stay at is 65-72 IMO(people argue w/ me on this but thats from my experience). If you go below 65 the growth will slow, the DO is higher the lower you go but who wants to wait forever for your plants to grow? If they go above 72 then you get into things like overwaterin,root rot(every DWCrs worst nightmare)...just all together bad things.


When you get everything started..start a thread and well help you through it
