How to get rid of cloudy water
 

Hi there. My levels are all good but wanted to know why my water is so cloudy? I have a fluval 405 with good carbon and i have water polisher as well but still is cloudy. I cleaned my filter, have good flow but wondering what i could do to clean this up?

Thanks

whats your setup like,your parameters.are you skimming ,over feeding,tank inhabitants,how old and kind of lighting.
cloudiness could be one or a couple of those reasons.

i have a 67 gallon tank with about 74 pounds of fiji live rock. fluval 405 filter. Tank is only 3 weeks old. i have 2 clowns which have been in there for over 1 week and look good. I added a regal tang yesterday and all seems good just want to clear the water if possible.

ammonia - 0
nitrites - 0
nitrates - 0
temp -78-79
alkalinity - 230 ppm
ph - 8.3

white cloudy or yellow cloudy?

your tank is in first stage of cycling 2weeks old tank is way to soon for the fish you have.read up on tank cycling.
you need water change lots of skimming good quality lighting and watch your fish closely.
does your live rock smells like ammonia:question: if so your live rock hasnt been cured,sorry to say save your fish, get someone to hold them for you untill cycle is over.
double check with those test readings.
lots of air circulation
lots of skimming
high water movement
often water changes
good quality carbon

I've heard of kick starting your cycle with a damsel or a chromis, but a regal tang???

Don't do water changes untill the tank is cycled. All water changes do is prolong the cycle. FWIW my tank took about 5 weeks to cycle.

he has fish in the tank for the cycle

Id do LARGE water changes and quite often

How are we coming up with tank cycling with these numbers? Assuming of course, the numbers are accurate, this is done cycling. So either cured rock, or the rock is dead and the cycle hasn't even started yet.
I would question the validity of the numbers though, NO3 should have a reading with a fluval...

My tank has cycled. I'm using good salt (bio - sea), i have fully cured fiji live rock. I started out with ammonia and nitrites on day 1 being .3 and no nitrates. about 3 days in the nitrates went to 10. on the 4-5 day ammonia and nitrites were 0 and nitrates were 5. I watched it for 3 days and no ammonia or nitrites and the nitrates were almost 0. Then i added 2 clownfish. I had them a week before i added the tang. My levels have been good all along with nothing over .1 since i added fish. Things are still fine. I test daily and sometimes twice. I cleaned my filter last night so could that be the reason? I have alot of algae but i have some turbo snails now that are doing a good job on them. My fish seem fine. They are eating good, swimming good, no signs of spots or damaged fins. I think everthing is fine minus the cloudnish.

Thanks
