Here is an acro the day I got it, and several months later. It was very bleached out and pale when I first got it, and had to acclimate it from the 216w of T5 from its source tank, to my 716w halide t5 combo. I used mesh screen from home depot, cut to be the size of my tank. Started with 4 layers and every few days I removed a layer. Sounds like a lot, but it is really about 10 seconds of work every few days.
Here are some pictures after a few months, you can see the growth and color coming in nicely. The first two pics are from 9/26 when I bought it, the last pic is from 11/27 so approximately 2 months later. I still think there is more green that needs to develop, but I have been getting nice growth. It may be time for me to move it up out of my sandbed, but I am hesitant because in this spot the growth has been great, I just want it to color up a little more. Im worried if I move it higher, I might cause it to get pale again. So for right now, I'm leaving it where it is, since I have no RTN or STN, Polyp Extension is great, and growth has been quick.
Is it normal for new growth to lack polyps for a short period of time? I think the tips grow first, and then the polyps grow, because my tips dont have the same PE as the main colony, but they do develop and by the time they have longer polyps, the next row of tips starts growing and the process repeats.
