ELEVEN MONTHS

Tank 1

I didn't do much about the two home aquariums this month until yesterday when I had some time to purchase some fishes and corals to stock up the tanks. Prior to this, I shifted some stuff to my office tanks. Yes, I probably forgot to mention this before but I have two nano aquariums in the office.

Anyway, I am still quite pleased with tank 1 because of the wonderful colours of the Zoas and others. Interestingly, this small setup proves to be very good for the LPS and softies because the mushrooms and Acans seem to thrive under these conditions. One of the Acans in tank 2 started to bleach previously under the high light intensity and low nutrients system and after being transferred to tank 1, it recovered well and is starting to look exactly like the existing grey and red one in the same tank. The Zoas are growing fast here but so are the purple filamentous algae, which looked sickly when I placed it in tank 2 previously. Every evening, I see the bluish-purple Actinodiscus mushrooms swell up to large discs and I think it is a haven for mushrooms. There are now 2 Clean Skunk Shrimps in this tank and one appears to be carrying eggs. I must also report success in netting the large crab in this tank last week and threw it into my main office tank with the bigger fishes. Hopefully it will be useful enough to scavenge the food scraps in the tank.

For tank 2, the algae problem persists because I still didn't do anything about it other than the usual scrubbing of the green filamentous algae on the aquarium walls. The introduction of the Yellow Tang did seem to provide some help in controlling the algae growth and it is working very hard 247. But even the foam sponges are now a media for the filamentous green algae to grow on. I kind of stopped dosing the Grotech and Polyp Lab products and have completely removed almost all the SPS and replaced them with more Zoas and softies although I do not wish to replicate tank 1's look. The newly acquired Peppermint Shrimp made a brief appearance when the blue lights were on but it is often out of sight. I continued to remove a few Zoas-eating nudibranchs over this month but it is getting less now and I am introducing the Zoas slowly. I am actually glad that this tank is a bit more colourful now and I will try the SPS again some other time.

DAY 317

After leaving the blue lights on for some time, I still found most of the sps showing poor polyps extension and colour. So I finally switched on the white lights and due to the sudden increase in white lights, the sps and some of my Yuma mushrooms bleached out.

Initially, I ruled out high phosphates as the possibility since I added lots of new Rowaphos in the Phosban Reactor. However, I still found lots of algae growth and turning on the white lights made it worse. Even my Clove Polyps were covered with lots of strands of green filamentous algae and refused to open up. Without a Yellow Tang, it does appear that the phosphates is an issue that I need to address.
