Opaque film???

Not sure what this is in my 210g FWLR... I was thinking maybe bacterial bloom (but my levels are good and my water is clear), or maybe some type of biofilm/algae? If you can ID it I would appreciate any help in clearing it up... it's all over the place. I run a reemat 500 + a octo 200 DC skimmer + 1/2 sump full of live rock + GFO + carbon. I have 2 variable flow nozzles and 2 Neptune WAVs that create a ton of surface agitation and flow. I've got a starts & stripe puffer (5''), tang (4''), baby snowflake eel (5''), falco hawkfish (2''), and a single clown (2'') in there. I feed about a 1/8 cube rods seaweed blend broadcast for the smaller fish and tang. The puffer & eel get fed with tongs directly... a cube for the puffer and the eel get about a 1/4 cube to himself.

So is this mainly in the sump, or...? I'd replace that steel clamp with a plastic one (completely unrelated).

stainless would be a good option there too, I don't 100% trust plastic clamps, or clear vinyl tubing, black food grade silicon is a better choice imo (unrelated as well )

It’s stainless… and that is my manifold under the tank that feeds to my media reactor

I will say even the stainless steel
Ones will rust
The metal within them does still contain some iron .

Unless you’re able to find true 316L stainless .

I swap them out for new ones as soon as I notice them rusting .
