So just this morning I noticed my water was a little cloudy (nothing a water change can’t fix right!) well I did about a 20% change. I come home 4 hours later and its so bad u can’t see through the glass, so I check the lvls 0 NO3 No phos and no ammonia. And I have nothing that large that could have died in my tank to make it that cloudy!! So desperately I’m asking u guys for help!! What do I do????? the only thing I can think of is 3 days ago I changed my light bulb to a phoenix 14k blue ( old bulb was odyssey 15k ). Also I run high activated carbon that I just changed out yesterday. thanks

Is it possible that something is just messing with the sand bed, with really fine sand when something moves it even a little bit you can get some hardcore clouds, that is what i am learning recently atleast. If not then we will probably need an entire list of water parameters and some other specifics(whatever you can think of) and maybe a picture so that we can see what is going on. Sorry I can not be more help.

lets see
salt 1.0023
alk 12
ph 8.0
cal 400
phos 0
NO3 20
NO2 0
i have a hang on the back refugium, which i have carbon running through it, and a built in protien skimmer, im running another protien skimmer that hangs on (both running 24 7) i have in the tank, 3 chromid, 2 bangi's, 1 clown, 1 tang , 5 peppermint shrimp, 1 cleaner shrimp. feather duster and flame scallop.
i think its because of the carbon i changed out, caused a bac. bloom ( white cloudy water) , but i did that a night before this happened.. so idk oh and i've hand my tank up and running for about 8 months now.

what color is the cloudy water?

[MonopolyBag]

may be very obvious, but try doing frequent water changes, twice a week small amounts. And maybe cut back on feeding?

Also, i had yellow tinge to my water, not cloudy though, before I added my protein skimmer, it does wonders.

[b4u]

its a white-ish color

makes it sound like someone said, sand flying up... you have very fine sand? can you see all ur substrate, no dougout places? and you could take a sample glass out n let it stand a couple hours, if micro bubbles they will disperce, if sand it will drop in the bottom... it just sonds like it will turnout to be a minor issue, since your tests are good

Hi b4u, my best estimation for your condition could lie with the scallop. Please read; INVERTEBRATE NON-COLUMN by ROB TOONEN

Flame scallops

Each month, I see a number of posts on the various reef message boards asking about what to do for a flame or flashing scallop that is in decline in someone’s reef aquarium. Although these animals are beautiful, relatively cheap, and easily available in the pet trade, I find that there is precious little information about them available. Therefore, I want to spend some time discussing the biology of these animals to help people understand why they typically do so poorly in captivity.

Just in case that didn’t sink in, I wanted to make a point of emphasizing that the survival record of flame scallops in captivity has traditionally been extremely poor. The typical experience of people who buy them is that the animal tries its best at hiding (often with the aquarist having to pick it out of the rockwork numerous times so that it is visible in the aquarium) for a while before eventually giving up and slowly dying. Even when the rest of the reef tank is flourishing, people who add a flame scallop to their tank typically watch as it slowly wastes away over a period as short as a couple of months to a maximum of about six to ten months. I would guess that the single most common cause for the demise of flame scallops in any aquarium is quite simply starvation. Although I should also point out right off the bat that these animals are relatively short-lived (something on the order of about three to four years maximum, and I’ll come back to this later), there are still precious few reports of these animals surviving in captivity for more than a year or so. Sadly, the 6-10 months that most people manage to keep a flame scallop in their tank is also a reasonable estimate of how long it should take a well-fed animal to starve to death after collection and being placed in an aquarium in which it is deprived of food. So, if you’re really set on trying to add one of these attractive and interesting animals to your tank, you need to make a serious effort to provide it with the appropriate conditions to keep it healthy and well-fed in captivity. Hopefully, by the end of this article you will have some idea of how best to go about providing for the needs of these beautiful animals, and I hope that we may start seeing some more reports of long-term success with keeping them in captivity.
So, as they die off they slowly they pollute the tank.
