help weid stuff growing in tank

i got home just now 2 noice weid stuff growing on eveything like someone drop dust in the tank i did a water change yesterday and everything was fine it was fine this morning or is it some thing that happens at night ? it like fine little roots covered in dust a sawdust colour on all the rocks and some corals what is it ?

 

I think that's calcium build up? I've had it on my rocks and in water before. It seems to happen overnight, but hasn't happened in my tank in a while.

 

will it hurt the stuff in the tank what do i do

 

Pics would help for a sure ID...

 

Pic would help, could be diatoms, phytoplankton or possibly dinoflagelates.

 

cant get pic on pc going to marine place 2moro for water checks and tell them whats going on

 

Did you kick up a lot of "dust" when you did your maintenance... you could have disturbed detritus that has now settled.

 

i put 2 new rocks in the other day and got 2 blue streak who made a hell of a mess when making there home burrowing the sand everywere it was cool 2 see but they keep picking up sand and droping it from up high it goes over eveything

 

Yeah I would say it is sediment most likely. Occasionally when my crabs move around in my LR I used to see what looked like a plume of smoke - turns out it was sediment/detritus from the LR, which the crabs were
"playing" in.

 

it me again i got pic on my phone what is the hair roots looking thing its everywere
