What’s with this RODI bacteria bloom?

[MONTANTK]

Finally starting to get my mixing station set up in my basement after being in my office for a few months. Went downstairs to grab some water for my ATO reservoir and noticed this bacteria in the tank. Never happened in my office but after a week in the basement it’s gone crazy. Any idea what’s causing this?

stagnent water in a basement can get bacteria. pretty easily.

I have a pump in there for circulation which is why I’m confused. Do you think I should cover the tank?

bac can still get in even with flow. RODI is zero TDS right clean the storage and have sealed when not in use yeah

Something's in your basement that's not in the house. Is it unfinished and a bit dirty (like mine)? I would cover it. At least it will all be dead once the salt goes in.

It’s a bit dirty. No worries, I’ll get a cover for it

Surprisingly it turns out some bacteria live just fine in either freshwater or saltwater, so I would not assume whatever is getting into the rodi will die after mixing. This particular bacteria may or may not be "bad" for the reef, depends what it is.

If your storage isn't air tight then atmospheric containments can/will get in, especially in higher humidity environments.
