Question about Coraline.

[lutz493]

Hello -
Had some carpet replaced this past weekend and tore down one of my tanks. This tank had extensive coraline growth on the back of tank about 85% coverage.
In all efforts of keeping it wet it apparently was able to still dry. I believe this has caused the color of my coraline to change from a deep rich purple to a faded out pink...
Will this ever regain its color?

Potentially if it keeps its color but if it turns white its dead and will never come back.

I have a problem. I have a 90g tank with alot of corrline on my rocks and the back of the tank and pumps. The other day it started bleaching out. It checked my water and the only thing that was off was the Ph it was 7.8 the rest nitrite 0 nitrate 0 PO 0 cal 440 Amm 0 water Temp 77-78 I have 4 110 VHO the lights are about 4-5 months old everything else in the tank is doing fine. If anyone could help please do. I am afraid I might lose the corrline on my rocks.

What is your ALK reading? What time of day did you take the PH reading?

Yes, it should regain it's color as long as you have good water chemistry and proper lighting,. (corraline doesn't need a lot). I've had it bleach completely white from a move or change and come back.

my first ph was taken about 2 hr after lights on then add some buffer over 2 days and then took test just before lights out and it was 8.5 alk was good my test does not give # just color and it was within normal limits cirulation is good I have over 900 gph with 3 powerheads and little giant MDQ-SC main pump

a ph of 7.8 is low. needs to be between 8.0 -8.3/8.4
