Another I hope simple question

Got up this morning, dust storm has cleared, but there is this white film looking stuff on the water surface, my skimmer has been wet skimming, and the cups are as far down as they can go, any ideas to what the film is, and will my skimmer clean it up?

As long as it makes it into your overflow, it'll be fine. Just wait it out a few days for your tank to finish clearing up.

I have no overflow, just a Emperor 400 for circulation running carbon, CPR Dual Bak-Pak Skimmer, with Bio-Bale 2 Maxi-Jet 600 Powerheads, soon getting more for flow

No idea what it could be from that description. I would give it a day or two and wait until everything in the tank is all clear and go from there. I would do a water test. Have you done anything different to your tank lately? Water change?

 

[cyeater]

Nothing different heres the last few days:

4/13 Friday: Rinsed sand in ro/di water (80lbs)
4-14 Saturday: Filled tank with ro/di water
4-15 Sunday: Mixed salt in buckets (37cups of Instant Ocean Reef Crystals) Started skimmer and was getting alot of brown looking skimmate (probably dust from sand)

The film is just the remains of adding the sand built up on the water's surface. Right now you have roughly 720gph of flow which is less than 10x of your display volume. My recommendation is at least 20x turnover minimum. Also, point one or two powerheads at the water surface to get some aggitation going to break up the film. I would definitely look into some more powerful powerheads to get the flow up.

Going to be getting MJ 1200's probably 2 of them for sure

Emperor 400: 400gph
CPR Dual Bak Pak w/ (2) RIO 600:1x125=250gph
(2) Maxi-Jet 600 Powerheads:1x160=320gph

Total: 970 gph almost 13x turnover but will add more
Is my math wrong?
