Dusty and dirty tank

[Nly]

I am a Vietnamese guy who is living in bay area. I have a 150g (48x30x24") that been running for over 5 months. This tank replaced another tank 5 month ago and the old tank is 125g (48x30x20"H), the old tank has crystal clear water.
The system has 75 gal sump, SRO-3000int skimmer, 2 MP40, 3 Radion Gen3 (2 Gen3 pro and 1 Gen3 normal), I run GFO, dosing three parts (CAL/MAG/Alk). As you can see in the picture, my tank is dusty with small white particle and micro bubble. The sump has bubble trap before get to the return section, I also put a felt filter sock to cover the pump inlet. I notice small tiny thing and few micro bubble alway inside the tank and water in the tank alway look like dusty/dirty all day long. All the equipment are the same with the old tank and the old tank has crystal clear water.
Any suggestion?

Probably micro bubbles. Try slowing down your return, you may have too much flow through the sump.

thanks for this valuable information.

where is your skimmer output and where is your return

Could be a saturation of precipitate from your 2 part dosing....? I would check pH, Calc, dKH and Mag and adjust dosing as needed (if you see an imbalance).

I'm thinking this as well. Also check your dosing lines. Sometimes if they're too close to the water they soak up and precipitate in the line.

For the micro bubbles the felt on the inlet can sometimes cause a lot of vacuum on the return hoses and they starts to suck air into the line. this happened to me once Either that or as suggested before it can be the return going too fast for the sump.
