Filtration problem. Help?

[kelseynicole2]

I’m still fairly new to the hobby. I have a 6 month old 37 gal tank, about 15lbs of live rock, and 2 bags of “live” black sand/gravel. It’s been clear water for most of the time I’ve been running it. However in the last two weeks, no matter if I change to a new filter media or clean it or wash all the pieces, the water has white sediment throughout all of it. I do 20% water changes weekly and recently did a 50% change this week to help the issue. I have also added phos filters and it seemed to help for a day or two but then went back to spewing the white sediments out. My black Darwin clown now has the same white spots/sediments on him and I’m worried it could be brook or ich. However the Picasso clown looks just fine. As well as my diamond goby and cleaner shrimp are looking/acting normal. Any suggestions ?

I currently have an internal aqueon filter that I plan on upgrading to the fx4 or something equivalent for my setup. However I am open to suggestions or ideas

Are you running carbon in your internal filter? If not that would help with the cloudiness of water. Can you post your parameters? That will help us also try and figure out what's going on
