So it's been a while, and I've been changing things in my little 43 litre tank, slowly but surely. The biggest changes have happened quite recently, and involved the addition of 2.5 Kg of Live Rock, and a Flame Scallop.
My little Anemone is, I think, a Ritteri, and if so, it might explain his bleaching, and yet, he seems to be doing OK under my relatively weak lighting. Nevertheless, it has been upgraded slightly, by 6 watts, and to half actnic. Now at 28 Watts total for this 44 Litre tank. Two of these are now in the hood originally meant for 2x 11 watt CF bulbs. I'll get a small fan if it seems like these start to overheat, but so far so good.
The 2.5 Kg of live rock was in three chunks that the LFS just finished quarantining. (So yes, it is a little risky throwing it in my only salt tank, but I have no isolation tank, nor the space to accomodate one right now) They are beautiful, and seem to have brought me lots of critters, including one that I'm not sure isn't an urchin. Take a look for yourself.
Otherwise, they're just covered with life,
To answer the immediate question, YES, the increase in live rock did cause an ammonia spike to around 5 ppm.
The fish don't seem bothered, but the Anemone and Flame Scallop seem a little shy at the moment. I've been changing water at the rate of 20 litres daily in two seperated 10 litre batches to take the head off the spikes until things even out again.
More pictures to follow.

He seems to be doing ok so far, despite the ammonia spike, and still shimmers when I shine a flashlight on him.
