The tank chores are done.
I started the day with changing the light bulbs. It always amazes me how much they change color from new to old. Definitely have to keep track of that as the spectrum shift is probably why the algae problem has cropped up.
Next, I spent the morning doing a water change. I used the siphon hose to pull the algae clumps off the top of the sand bed. Once my 5g bucket was full, I took some of the bigger rocks and swirled them in the bucket before taking a toothbrush to them. Needless to say, the old water went from clear to brown. Four buckets later, all 16g of fresh SW are into the tank and hopefully lots of crud OUT of the tank.
And 3: Changed the GFO. Necessary to get things back on track.
Oh, and I did a little shopping...
Acan Echinata
Another Brain coral. This one has a different shape and green sides. Hard to see where it is now.
On the left is a purple lobo and on the right is a prism favia.
In the back you can see the Orange Sherbert Montipora.
And here is a purple and green acan (left) and a green torch (right).
