I'll give it a few days for the filter to do it's work. Is there a way to tell if the filter is doing a good enough job? Currently the filter pressure goes from 12 psi to 22 psi in around a day or a day and a half. While backwashing, the water looks pretty dirty and takes around 2 minutes to clear up. It seems normal, but just wanted to make sure.

The fact that your pressure is increasing, along with dirty water during backflush, tells you the filter is working- the increase pressure is due to clogging with debris, which you then rinse out during backwash.
Note, a slightly dirty filter works better than a clean one, as the partial clogging also makes smaller holes in filter media to catch more crap- partial backwashes more frequently will often reduce total time cleaning the cloud out of the pool, but at end do a double duty backflush to make sure no residue left in filter; decaying algae can give more "food" for future algae, so you want all that crap out!
