Here are some before & after growth shots from the beginning of February to present. The Red Dragon before shot was from Sept of last year. This is still relatively a young tank as it has only been up and running for exactly 1 year now. I would say the first 6 months were pretty bad for growth and colour. The last 6 months I have really seen a big difference in both.
Tyree Pink Lemonade. This thing took forever to grow. I actually had this frag for about 1 1/2 years. It did nothing in my old tank whatsoever and pretty much only took off over the last 4 months I would say.
Tyree Red Dragon. Actually got amazing growth as this is typically a slow growing coral. Not bad for 1 year.
DV Candlelight. Not a ton of growth over 6 months but it has easily doubled in size.
Tubbs Pink Jade - This has really grown well over the last 6 months. I even accidently fragged a large branch off when I bumped it once.
Ultimate Bonsai - This has really taken off as well over the last 6 months. The colour is amazing now and has really only got nice and bright over the last 2 or 3 months.
Tyree Setosa. Another notoriously slow grower. It is doing its thing though and the colour is just getting deeper and brighter by the day it seems.
RR Gold Bar - Here is one that did absolutely nothing for 4 months until Feb where you can see some little tips starting to grow. Over the past 6 months it has easily quadrupled in size.
ORA Hawkins - It actually started growing right when I got it and just keeps going nice and steady. The branches are growing really tight together and the colour is just unreal. One of my favourite pieces!
Here's a shot of my Red Acro and DV Limeade. Both have grown nicely but that Limeade grows like a weed!!!
FTS Comparison. Lots of things have moved around and I lost my massive Hollywood Stunner.

It's in frags now... You can see the big change in colour though. Some of it is the photo I am sure but the colours on my SPS is 10x better than 6 months ago.
