My ph is 6.5 ( Low, I know. Trying to raise a bit. )
Some tips of his fins are a Bit Curly, but not all. My ph is low, though.
Isn't the Curling supposed to be Caused by the Hardness? I never knew it was because of ph too... Anyway, what's yours? Is it above 8.0? ( This is Highest? )
If it is, THEN it's too high. Ph Down? It might help.
