Tank cloudy during fallow?

[SaltwaterGuruNeeded]

Why would my fallowing tank of about 1 - 1.5 weeks be cloudy? Should this be of concern? I have a microscope if you'd like me to take a sample. Tank is 4 months old, fallowing for diseases for 1.5 weeks so far.

Did you just set it up and fill it?

No it will take some time while filtration breaks in and all the dust settles.

No, running for about 4 months, then started fallow.

Did you rinse your sand? Filter floss may helps if you don’t already use it.

Not a new tank.

I do use filter floss. And sand is relatively clean by now.

In that case must be bacterial. It doesn’t look too bad. Maybe UV would remove it. We are just guessing

Well, my uv broke during the start of fallow. But didn't think it would make my tank this cloudy.

Let me take a water sample and send some pics in.

 

[SaltwaterGuruNeeded]

Yeah, it's bacteria...Not seeing much up to 400x

 

[SaltwaterGuruNeeded]

Also don't see much of anything at 1,000x

 

[SaltwaterGuruNeeded]

This is what I see...

Bump: added like 1/4 of a biospira bottle that treats for 75g right before fallow. The other 3/4 was put into qt tank. Thought it wouldn't hurt. But tank is still getting progressively cloudier.

Bump: Still getting cloudier...

You need a uv it you can just wait it out if no fish/ corals in danger

I believe it to be a diatom bloom... I'm making a new post. Yes I am working on getting a new uv.

Diatoms are on surfaces and brown. The cloudiness is not diatoms.

Well, take a look.

I have looked at it. The most common types are a cigar and the triangle shaped ones for diatoms.
i am no expert but I have looked them enough because I have dosed silicates for dino treatment none of your pictures or videos contained ones I recognise.
