Frogspawn Health Question

[mbcolangelo]

I'd like someone's opinion of what's going on with my frogspawn. I'm noticing a color change on its base but being new to the keeping corals I don't know if it's good or bad. The 3 images show it around the time I got it, at night closed, and open under lights. I first noticed this a couple weeks ago

This morning

Normal pic of it open

Around time I got it - about 45 days ago

Tank is about 4 months old, 55g (75g ish total volume with equipment)

My parameters are
Sg: 1.022 (I have a junk float tester atm)
Ph: 8.0
Ca: 400
Kh:9.6
No2/3 & nh4 all 0
Temp: 76
I've reduced my dosing of c-balance to 5ml every 2 days (I'm considering reducing it more due to Kh level) - I've noticed this color change prior to my dosing changes
I do 3ml Combisan weekly

I don't really see the change in color, but it looks like a very healthy and beautiful coral!

In the first pic at its base the light colored spot and lighter color below that. Is that just normal growth? It's not slimy or anything.

Thank you for the compliment too!
