Question Cloudy water overnight?

So I recently purchased a new piece of driftwood which I boiled for several hours to remove the tanins. Inevitably once I put it in my tank the water was still tinted a light amber color. It didn't bother me at all, looked nice and the neon tetras seem to like it. End of the week came and I did a 30% water change. This morning I awoke to very cloudy water. It is not like the driftwood tint but a murky white cloudiness. Any advice on what might be causing this?

My water parameters are as followed,

Ammonia: 0ppm
Nitrites: 0ppm
Nitrates: 5ppm
PH: 7.6
High Range PH: 7.4

If it doesn't go away in a few days, it might be the wood.

Only heard of haven't had first hand experience but it could be a bacteria bloom like brown diatoms in new tanks

if its white and milky, definitely a bacteria bloom

completely harmless and best option is to wait it out (will take about a week IIRC)

I honestly LOVE bacteria see your tank and it bothers you and it bothers you and it bothers you...and just when youre about to give up and do "something"

BAM! crystal clear water! and you feel LIKE A BAUS!

White cloudy water is rarely the driftwood. Maybe related, maybe not.

1) The beginning of green water algae. It does not look very green right away. If you have white floss in your filter you might see it as green. Within a few days it will turn green.

2) Heterotrophic bacteria. These are good bacteria, just not the nitrifying species. They are eating organic matter in the water. This is where MAYBE they are related to the driftwood. But since you boiled it, I assume you also rinsed it well, so there should not be enough stuff coming off the wood to feed these bacteria. Maybe. A water change and substrate vacuum might help.

3) Somebody dropped something in the tank. Cheerios, Jell-O, all sorts of stuff can end up in the tank. Water change, vacuum the bottom, clean the filter.

4) Ammonia rising. Often shows as bubbles that do not pop as easily, too. I would sure monitor the ammonia and be ready to do a water change.

5) Adding minerals to change the pH. Sometimes the water company changes what they add to the water, and even through you have not added pH altering materials you get this effect when you do a water change. Are the pH, GH and KH the same as always?

Some recommendation (not definitive, but your choice)
1) Increase carbon/floss filtering
2) Airstone
3) Add powerhead circulation.
4) Equal temperature water changes.

I always try to keep tank water circulating in a CW or CCW direction.
