Cloudy water

[JVan82]

Need some help never encountered this issue before. I have had my IM lagoon 50 set up since mid Nov. Water has continued to be cloudy, in the last few weeks. I have a sicce 2.0 return pump, 2 MP10s, XR15 gen 4 pro. I started curing/cycling the rocks starting last sept, roughly 25 lbs rocks, and 40 pounds sand, used the clarifying packs that are in the sand. Even cycled tank once rock and sand was added. I have ran the 11oz chemipure blue, changed every month. Run intank media rack and floss holder, holding poly-fill changed daily. I have 3 of the marinepure blocks (not marinepure cant remember the brand name) and were soaked in microbactor7 over night as stated in the directions. Have done 4 gallon weekly water changes, since cycle was completed. (36 gal total volume) Last sunday did 8 gallons. I have always used redsea coral pro salt. (Also have a IM lagoon 25 same salt, water and water change schedule) parameters and pic below.

Ammonia 0
Phosphate 0
Nitrate 0
Calcium 410
Magnesium 1400
Kh 9.0
Ph 7.7-7.9
All tests are redsea and ph is from apex probe.

If those measurements are accurate, without knowing anything else, your system is dying from starvation.

Cloudy normally means excess bacteria. UV will address bacteria as the symptom of insufficuent biofiltration and a build up of DOC. Granulated activated carbon media is 300% more effective at removing DOC than a protein skimmer.

Just a thought. Happy reefing.
