White growths on axolotl tank decor

[Megg]

Can someone help me identify the small white growths on the brown bridge decoration.

This is a new tank. Had cycled. Some sort of massive white "bloom" was in my canister filter and one day just started pouring from the hose.

Did big watwr change sifted out and rinsed filter in tank water.

Everything has seemed fine. But now I am paranoid!

Just curious if it's bacteria, algae, fungus mould. Should I be leaving this or trying to clean it out.

Thanks

Probably a bacterial growth - I would just make sure the water parameters are good and stop worrying .
