Try a product by Sea Chem, it is a water polisher.
I bought a water filter to use on my kitchen sink for my aquariums. That cuts some of the guess work in figuring if the aqua is safe.
You can also make your own Media Filter to help add more of the good bacteria to safely break down the food and waste.
What size of aquarium are you working with?
