?? Paddle sponge ??

The top of my paddle sponge is starting to turn a translucent white color do you think may be do to my recent temp spike? it is only about a 1/16" of the top of it that has changed. Or is this normal maybe it is growing?
I have had the sponge for about 2 months and it has been doing fine but recently I forgot to turn my air on in the room my tank is in and the temp in my tank went up to 90 Degrees and I lost my Colt coral I just tested my water here is the results.

Alkalinity- 8.3
Calcium- 410
salinity 1.025
ph 8.2
ammonia- 0
nitrite- 0
nitrate- 0
temp - 80
Thank You For Any Help ...................... John

There is some info near at the bottom of this page

Looks like you may be able to cut out the dead areas and the sponge will regenerate

Thank you John

 

John,

I know very little about sponges, but I have seen them get the white translucent areas near the top. The area slowly moves down until the whole thing is dead.

I guess a bit of pruning now might stop the process, but don't take my word for it

John Do you know what you would use to trim it off with?...................... John

 

John

Well, I would use something very sharp like a scapel and make sure that you do it underwater.

Don't just go ahead and do it though John, wait around until someone who knows a bit more about these things turns up The reason I say that is I believe that some sponges can release toxins.
