I think my problem is the 100 micron polishing pad just isn't catching everything. It has definitely improved water clarity but it's still not perfect. I may look into the 60 micron pads you suggested even if it just on a temporary basis to clear up after gravel vacuuming etc.
I really don't think its due to the tank being planted. I find a lot of "stuff" if my filter sponges so I'm pretty sure water flow is good.
As for the tank being relatively large, the 406 is rated for up to 100g so nearly double the size of my tank
. I also considered adding a HOB
but I just don't want another filter to manage and more equipment on the tank. I think the 406 should be enough.
I am curious about your experience with Purigen. I have been toying with the notion of using it instead of the Chemi-pure.
But the guy at my LFS
convinced me to stick with Chemi-pure (they carry both products so I believe he was being genuine). Any issues you are aware of with using Purigen in a planted tank?
I will also give filter socks a look. Hadn't considered that!
I agree you have plenty of filtration capacity and at 383 GPH
Fluval 406 External Canister Filter Review | Tropical Fish Site
your ratio of GPH
to Tank size is almost 7, which is excellent for a canister set up. However, just because you are catching lots of debris, doesn't mean there aren't "dead spots" in your aquarium ....... or that the current generated by the 383 GPH
flow is sufficient to draw detritus from all ends of the tank.
Since you see visible particles in the water, let me suggest this as an alternative. Put in either an air stone or some cute bubbling devise to stir up current at the opposite end of the tank from the filter intake. This would stir it up enough to get it into the regular "inflow" current of the filter intake. Or, if the filter intake is at one end ....... not sure if this would work ....... but try moving the intake to the center of the tank .... if you can ... or if you can, put the intake at one end and the outflow at the other. (I don't know if that's possible).
My aqua-tech 30-60 HOB
had a 330 GPH
flow and was drawing from a tank 36 inches long ..... but seemed to catch all debris that I wasn't siphoning out during regular water changes. Your tank is probably 48 inches or so long and the distance might be too far for a 383 GPH
intake ...... again ..... just a thought to get optimal circulation from throughout the tank to the filter intake.
As for Purigen, I'd ignore your LFS
guy. He probably believes he is correct .... but based on the bazillions of reviews and discussion of this product, Purigen wins hands down.
If you started a new thread called Purigen vs Chemi-Pure, I can tell you Purigen would be the hands down winner. It works GREAT for me for keeping parameters in check. I bought it based on all the rave review for it on this forum and purchases reviews on Amazon.
Also, Amazon sells the 100 ml size for $8, which is about 60% of what local LFS
charge. It lasts 4-6 months and can be regenerated (although, I plan to just trash it when it is fully used up)

[note the 5 star rating. Also, I had never even heard of Chemi-Pure until you mentioned it this morning ....... and then I was at PetLand early this afternoon and their employee .... who has a salt water tank mentioned it out of the blue as great stuff for salt water tanks when I was there to buy another fish for my 29 gallon and mentioned I use Purigen. So it must have a decent following]
Best wishes and good luck.
