I can say from personal experience that CPE DOES make a difference. I can tell overnight the difference. Less algae on the glass, clearer water etc. Now I have O3 in there with all of that... My water is SUPERDEDUPER clear.

Seriously, I say this over and over to people. RINSE YOUR FOODS!!!! It makes a HUGE difference. Feed every TWO DAYS, not every ten seconds unless you have items that have to be fed.

Just that alone should help to alleviate much of the issue.
