have a white out problem

[JUSTINSREEF]

i noticed all my coralline algae is turning white and im kind of new to the hobby i have no idea what is going on and some of my corals are turning white too.. please somebody help me..

Need more info. How old is tank? What lights? Are the coral that are turning white new to tank? What are the water parameters? Calcium, mg, and alk also.

Did you let the water level get low and expose the coralline to the air? That happens in my tank.

the tank is 5mths old and the i have 2 t5s 1 actinic and 1 white and 4 compacts 2 actinic and 2 white and in the process of getting a new light fixture. would it be that i only have like 40# of live rock for a 75 gallon tank.. i have 45# of live rock coming in next week from liveaquaria.com. i guess i need to get a tester for the calcium.. the only thing else that is wrong is the salt is a tad high..but i am going to do a water change..and i have had the purple mushroom for 2 weeks and it just now started to turn..i think it might be the calcium level.. anything else you need to know just ask and hopefully we can figure this out... any info is greatly appreciated..

no its happening from the top all the way to the bottom.. its weird i have never had this happen in my past tanks..

Your alk may be off, one of the most important parameters to monitor.

Agreed I think it may be an Alk problem.

My first thoughts were air exposure, Calcium, Alkalinity or Temperature. Since you've ruled out exposure to air, I'd look at your Calcium/Alkalinity balance and make sure your temperature is staying stable and at appropriate levels.

sounds like water params are off like already said. you need a dkh and calcium test kits, magnesium would be good to!!

Several possibilities, as mentioned above first check water parameters alk/ca and also phosphates. Could also be a change in lighting, shift in spectrum from old bulbs

vegas glad u said something about lighting, my coraline went white after i went from t5 to halide. i was wonering myself if that was a possibility

happened to me when my alk was off
a few water changes and i was right back on track
