I think moving your intake more toward the center would help. Also try rotating your spray bar so it is almost straight down along the tank back to get the crap into the water column. You have a lot of finer filter media that can slow the flow & need more frequent cleaning than I like to do on canisters especially.
I use 2 filters on almost all tanks, both for better flow & crap removal. I only clean filters when the flow slows. But I also use sponge prefilters on intakes to keep big stuff from clogging the filter media. Those will need cleaning every week or 2 but it's very quick. I use running tap water & squeeze the heck out of them for a couple minutes until most of the "stuff" is rinsed out.
Whitish sand shows everything. I use pool filter sand, that, with some practice, can be cleaner. I use shallow vacuuming & a swirling motion around plants to kick up debris without disturbing roots. Finer sand is harder to deal with & can compact possibly causing the anaerobic pockets mentioned. I'm used to the more speckled look of sand, lol.
