Max,
I've not attended any photography courses, I just enjoy taking pictures. I suppose you could say it's my other passion, after reef keeping. Now that I have a digital camera it's so much easier too. Delete, delete, delete...
I'm thinking now that the algae could possibly be
Udotea sp. Well, whatever it is I hope that it keeps small and manageable.
Rob,
Thanks!

The rocks do have a secret support. I've not posted about it yet as I wasn't sure if anybody would want to know about it to be honest but since you've asked....
I wanted the rocks to be secure but avoid using the likes of milliput etc, so I picked up a length of 6mm acrylic rod and made a frame using it. I cut the rod into 3 smaller lengths and glued them (using Tensol 30) to a bit of acrylic sheeting (black was all I had available at the time). The small squares at the base of rocks have holes drilled through them and sandwiched together with glue as I wasn't sure if the rods would be secure enough without them.

The LR was broken into smaller pieces using a hammer and a hole drilled through the middle bits. Then the pieces were threaded onto the rods to form 3 stacks. Nice and secure but not obvious when viewing the tank. The thin layer of sand hides the black acrylic sheet.

There's been a bit of a development in my Pico since I last posted an update, the pink
Seriatopora is no more.

I had to remove it, but not for any of the reasons I expected. I have already mentioned that my zoanthids were looking a bit rough the other week, I thought that I had cured the problem by adding some carbon/polyfilters in a bag to the refugium but it proved only to be a short term cure. Soon afterwards the zoas were losing colour again and refusing to open fully. I changed out some water (multiple times actually) in case it was a water quality problem and even stuck the carbon/polyfilters into a proper pumped filter unit in case passive filtration was not efficient enough, but the zoas continued their downward spiral. On the morning they refused to open up at all I decided I must take other action. The only change that I had made to the tank prior to the problem developing was to add the
Blastomussa corals and
Seriatopora. Now, there seem to be a fair number of Pico tanks (in this competition too) with Blastos in so I figured that they were unllikely to be the cause of such problems but I haven't seen many
Seriatopora mixed in with zoas. I didn't think that it could be the root of the trouble but I wasn't entirely sure so I decided to take the frag out and see what happened. To my very great amazement the zoas immediately began to open up again and after 3 days all are pretty much back to normal again. I never knew that
Seriatopora could pack such a potent punch! There's always something new to learn when keeping reef tanks.

I had actually been quite pleased with how the
Seri had been doing up till then, it had been keeping its colour well and showing signs of growth too. Oh well, this Pico was never supposed to be about SPS corals. I took a quick pic of it before it was banished to the sump of my big tank to show how it had been faring, there are 6 days between the left shot and the right shot.

Best regards
Ann
