TEN MONTHS

This is a month of little change. In fact, I shifted a lot of the corals around the two aquariums and moved some to my office tank. These days, capturing the photos is a problem for me because somehow my iphone and Nikon cameras are unable to record the true colours of the fishes and corals.

For tank 1, I still find that the assortment of Zoas provides a richer palette of colours. 

For tank 2, there was a significant reduction in corals. For October, there were only additions of 3 rocks of Yuma and Actinodiscus mushrooms and shifting of some of the rocks and Zoas. Unfortunately, this tank suffered a nudibranch attack, presumably from some corals that I last bought. Things are still not under control and sadly, the Zoas are not opening up optimally. Things are also not looking too good in this tank because I have problems maintaining the kH of the water. I am left with only a few pieces of SPS and the green and red digitatas have almost lost all its colours. I guessed it was due to bleaching under the 80-100% of the white intensity of the AquaBeauty LED lights but I have since reduced it to 10% daily but there is still no improvement. I suspected the phosphates were high since I started seeing the appearance of algae and had since replaced the phosphate removers. Ruling out the high light intensity and phosphates as the causes of the poor appearances of the SPS corals, I can only suspect the water quality as well as the delicate balance of kH, Mg and Ca as the principal causes.

Another astonishing thing for me was also the discovery of one big crab in each of the two tanks. The one in tank 1 has a rougher exoskeleton while the one in tank 2 looks like a solid black. They looked menacing to me and I wonder if they were accountable for the disappearance of some fishes.

As for the LED lights, whilst I did receive the Maxspect Razor 120W early this month, mounting it proved to be an issue. Hence, I replaced back the AquaBeauty.
