Yesterday I opened my filter to clean it out. I put it back together, and added the approx. correct amount of cellulose (I eyeballed it), then I vacuumed my pool.
Today I unfortunately noticed a small leak in the corner of the filter. (I had skipped the step of re-lubing the o-ring and I'm sure that's what it was.) So today I opened it up again to fix it. When I opened the filter to re-set things, this is what I saw:
Is this correct? It seems like the cellulose is very unevenly distributed. Large areas of the fins have no coating at all. I have no idea if it takes the cellulose a while to coat the fins evenly, or if I did something wrong. (Too little cellulose? Added too fast?)
Secondary question: some of it already looks pretty dirty! Is that normal? Some of it is the color of the last few months' worth of dirt accumulation which I just hosed off!
I'm pretty sure the answers to these questions would be the same regardless of whether I'm using DE or cellulose, since the coating and the dirt-catching properties are so similar.
