Forest fire digi problems

[Mcardle2012]

I have 2 pieces of forest fire digi. Both look pale and with no polyp extension . They are in a 65 gallon tank with an ati 6 bulb fixture . I have the coral about half way up the tank . Any help would be great .

What are your levels? They are very sensitive to Alk levels/swings.

I've been working a lot so havnt been testing as much as I should .
