Water Murky

[Clawfish]

Hey all, I have a 65 gallon reef tank, cycled about 15 weeks but noticed about once a week for a day or two the water will get “milky”. I added a photo of my sump, reef octo 110sss skimmer and sock/heater in chamber 1, marine pure block and chateo in 2, one of the three noodle bubble trap i left the, i have 11oz bag of chemi pure blue, purigen and just now added a bag of carbon to help clear it up. Will the carbon help?

chamber 3 is return pump, ato and green killing machine 9watt

thanks all!

EDIT: I don’t want to run the uv too much since the tank is still maturing. water changes are 15 gallons every two weeks but the milky/murky water seems to be at random

Sounds like some kind of bloom. Does it coincide with any specific food or dosing around that time?

Not really I did have phosphates around 3ppm yesterday so i dosed a little phosguard. was clear until around 10am today today they’re around 1.8ppm and haven’t added anymore

That sounds really high or am I misreading the numbers? Most try for .03 or less.

they have kind of stuck around there last week that’s why i got phosguard. i have just a pair of clowns now but it’s weird that now it’s getting cloudy and the phosphates are dropping, unless i’m missing something.

I’ll keep up with the phosguard. should i run the uv? i changed 15 gallons this am but it was few hours after it for murky
