Foggy Water

Hello Everyone, My 10 gallon planted tank water has become pretty foggy after a water change and filter cleaning. I know i did not harm the beneficial bacteria because i rinsed the filter fiber and pad in the old tank water and not tap. It has been 2 days now and it is still foggy. Should i do another water change? My tank has wisteria, Lutea Crypt, and a Banana sword in it. The inhabitants are 4 Silvertip tetras, 4 Neons, A platy, and a Dwarf Gourami. I do weekly 20% water changes on a strict schedule. Thanks.

I wouldn't worry. I see this in my tanks with canister filters after every rinsing of the filter, it takes 2-3 days for the water to return to its normal clarity. You have messed with the bacteria in the filter media; there is a host of various bacteria living there, beyond the nitrifying strains, and this disruption can often (usually) cause a bacterial bloom.

If you want to read more about all the bacteria, have a look at this:

After a water change some slight cloudiness is also common. This can be due to suspended particulate matter in the tap water [viewed under a microscope, you might be surprised at how much stuff is in the tap water], or again to the bacterial bloom. Tap water is high in dissolved organics, and this feeds bacteria, as that article I linked will explain.
