145g Reef Tank - Tank Log

Date Event Type Notes
30 Sep '07 Calcium Reactor Upgrade A couple of weeks ago my Deltec PF501 Calcium Reactor finally gave in - the shaft/propellor cut away at the blastic bushing and thus stopped working. Replacement parts will take anywhere up to 3 months, and in 2 weeks time my Alkalinity dropped to 4dKH and Calcium to 340mg/L. So I had to take a drastic measure and purchased a Deltec PF601 Calcium Reactor. It is exactly the same as the PF501, just much bigger. I have just managed to set it up and so far it is running fine.
7 Sep '07 Lighting upgrade I discovered my montipora was starting to grow upwards in a cup like fashion rather than a plate like structure. This, together with several other indicators prompted me to upgrade my lighting (8 x T5 54W). I purchased a Giesemann Infinity pendant that has 2 x T5 54W Actinic, 2 x T5 54W Aquablue+, 2 x 250W Giesemann Coral MH. I removed the canopy's lid and the new light fixture is hanging about 25cm above the water level. Go see the tank versions page for pictures showing the increase in lighting.
21 Jul '07 Livestock acquired After numerous discussions with the guys over at ReefCentral and WetWebMedia, I decided the reason my Chromis died were not due to bad water quality or some spreading disease. So to replace the lost school I purchased 5 Anthias which is currently in QT. I also got a long spined urchin to replace my rock urchin. It is still a baby so I hope it does well.
19 Jul '07 Fish Died

My second last chromis showed exactly the same signs as the chromis that died a month ago. It had some scale damage on its body, as well as weird fungus like growths on its fins.

I moved it over to the QT tank, but it died within 8 hours.

16 Jul '07 Urchin Died My Rock urchin just died. The past couple of days it started coming out in the daylight and just sitting on the substrate. This morning it was dead. I have no idea why it died.
