Some mushrooms turning white?!

[attilak]

Hi, so I am recently experiencing this strange changes in some of my mushrooms. It is an LPS, softy tank and most everything except some mushrooms are turning white. Has anyone run into this before? I know that my phosphates are high but nitrate at about 5. All other parameters are right on where they should be.

Wait are the mushrooms turning white or the other corals? What is the highest your temperature gets and what is your alk and po4 readings?

its some of the new mushrooms I had purchased recently... other corals are fine. my Po4 is 1.0. can't seem to lower that and was possibly looking at dosing NoPox. Nitrate is around 5. honestly I think higher nitrate / phosphate should be ok for mushrooms. My temp is around 79. it fluctuates between 78 - 80. I have a chiller on the tank otherwise it would be higher! the older red sea's run hot which was one of their issues.

Po4 is one point o(1.0) or point one o (0.10)? I would suspect that first if it is that high

I use the hanah checker. showing 1.12. unless I got to do some other math, it is 1.12 ppm. I have always had this high phosphates and even cut back a lot on feedings. I only feed once a day now frozen. Everything else is good and growing in the tank. I was thinking that maybe lack of iodide??

They can sometimes turn white in very low light.

Could it be you're reading ppB in which case 112 would be 0.34ppM

it's interesting about the hannah checker as I am about to post another thread. It seems very odd because the hannah checker does say "ppm". tonight I checked it it is actually showing 2.5! but I did a quick test w/ salifert and based on that test kit I am at .25 ! I am glad I did this check as I was about to dose some PhosBan-L.

In regards to lighting Randy; I actually just replaced all my T5's as I do every year and also have a PAR meter.
