I have had cloudy water twice both times in the first year of my 75 gal.

the first time was due to a mini maxi spawning the second time was due to bacteria bloom @ the 5 month mark. took a few days to clear up using carbon.

I've got cloudy water last few days and it puzzles me. My Red Planet is loosing the skin. My parameters:
1. PH 8
2. PO4 0.06
3. Ca 530
4. Alk 9
5. Salinity 1.026
6. Temp 25C

Recently I added BioPellets Reactor less than a month and I am using Live phyto and live pods. Mainly my SPS reacted. Red planet lossing the skin. Acro loosing Blue color, Pocci doesn't extend much. Other corals like hummer, acans, zoa frogspawn are ok.

Any ideas? Did 20% WC still cloudy. Thx

It's your biopellets reactor, You have bacteria bloom
At this point you will have to remove the biopellets for 2~3 days
And add air pump as the oxygen level will drop and my kill your fishes
Do water change .
U can save your used biopallets media, just wash and dry the media
When you are ready for the biopellets make sure ad enough as directed or a bet less for your total water volium . And make sure 100% all the media tumble
If you using maxi jet model 600 or under you will have to upgraded to minumum 900 but 1200 is the best for this job

Thank you everyone for comments. Will wait until next water change and see the water parameters and will decide afterall.

So over the week I had:
PH range 7.8-8,2
Alk 8.7 dropped to 8.3
Ca 450 dropped to 370
PO3 0.08-0.00 and back to 0.06 - I think my feeding affects PO3.
NO3 is 0.00 all week.

It is time to do waterchange. Should I go ahead and do WC, how much? should I try to dose and keep Alk and Ca consistent? How I can drop Alk to 8.0? I am using H2O salt at 1.025 salinity.
My pocci finaly is puffy, but I noticed my Powder Blue Tang has itch I think. I gave her garlic veggie

Thank you

Last time i used BioPellets in established SPS tank I lost about $450 worth of my best SPS corals.
For the fish itch you may want to consider a UV light.

As for the water change better to do more frequent but small water changes.

To drop Alkalinity add Magnezium http://www.jlaquatics.com/product/sc...+600+Gram.html
"Severely depleted levels of magnesium (below 800 mg/L) can cause depressed pH levels and an inability to maintain proper calcium levels. Magnesium depletion is commonly associated with the use of kalkwasser"

With small but frequent water changes your water chemistry will stabilize
.

Not sure how big your system is but I do two 5 gal WC a week on a 30g system and works great....for now

But as coral grows it will deplete the major three a lot more

And yes your feeding does affect po4. Try target feeding rather than broadcast
