Quick update/question (of course

)
I made a little bit of an impulsed buy...A BTA and a couple captive bread percs.
NOW, the question...the BTA was pretty big in the store, but I thought it wouldn't be too bad. I got it home, and two days later it spread out to like half the width of my tank. I'm assuming that this will effect my bio load? Will this be too much load? Does the mushroom that doubled in size going to effect my bio load?
FTS (my DSLR is at a friends, sorry for the crap pics)
The culprit
The mushroom thats growing...
The tank is doing great, I am just worried about the size of these things...also, notice the new star polyp! I love it! Color is crap in these but it look florecent!
Thanks for looking!
