white stuff

[Carl C]

hi there community. i have a coral QT tank i recently set up and even more recently put 2 zoas and a anemone in there

on my heater this white film forms and then flakes off ; the filter might catch some of it, but some of it settles on the bare bottom tank bottom. my anemome is covered in it and hes not a happy creature ive tried blowing it off him with a low flow powerhead ; its stuck there pretty good, so either he will have to remove it himself (or not)
anyway the question is what is this ? i've done some googling and have seen the question posed (rarely) and people answering that "maybe" its calcium ? anyway just putting it out there ... perhaps someone has experience with this ?
thanks Carl (Boston)

Pics?

 

[declanisadog]

Pictures would be helpful. Is it stringy at all, or more filmy? soft or hard?

If it's hard could be calcium carbonate precipitation but that would probably only happen if you were dosing this tank or using kalk?

Pic of heater and that little snowball in other pic is anemone

I would give that heater a vinegar scrub as well as clean up some of the detritus during a water change. I'd also check your alk/cal as these can drop drastically during some precipitation events which could be upsetting your corals. Hard to tell much from the pic of your anenome. Here's Randy for some info on some types of precipitation.

Yeah, I would just do my best to clean it all out, and see if it comes back.
