It is a great honour to be chosen as the Featured Aquarium byAdvanced Aquarist. It gives me great pleasure to present my tank toyou.

How it all Started

The tank was started in September 2003, in fact as a result ofthe Finding Nemo movie. What was meant to be a casual discussionwith my daughter, after watching the movie, evolved into a marinetank, after some mild objection from my wife and many marineaquaria books. Needless to say, Nemo and Dory were stars of thetank; it was after all due to their influence.

The tank initially started as a mainly fish, softies and LPStank. The initial setup was done by a local LFS here (Marine LifeHobbielist) as even after lots of research and countless books, Iwas not confident enough to do the first setup on my own.

As my tank matured, and as fishes come and go; I was attractedby the excellent looking tanks posted in various forums andbulletin boards, especially those with SPS in them. I startedplanning for the next level and embark on SPS in January 2004. Istarted upgrading equipment, lights, protein skimmer, calciumreactor and chiller. Before I know it, I was stocking frags andfinally some colonies.

At the end of a hard day’s work, it is extremely relaxing andsatisfying for me to see growth and colouration of my SPS (much tothe dismay of my wife). I was also very glad I shared this hobbywith my children.

Aquarium Profile

Lighting

I started with an Azoo MH with 2 x 150W and 2 Blue PL. When Istarted on SPS, I upgraded the lights to the followingconfiguration, placed 7 inches above the water:

Equipment_Lights.JPG
  • Metal Halide Aqualight with 3 x 250W 10,000K BLV DE
  • T5 DIY 2 sets of 4 x 54 W tubes each. Each set consists of 3 Aqualight Coralblue and 1 Aquaz actinics.
Photoperiod
Light Duration
1st set of T5 0830 to 2200 hrs
2nd set of T5 1000 to 2400 hrs
1 x 250W 10,000K MH 1230 to 2130 hrs
2 x 250 W 10,000K MH 1300 to 2100 hrs

Water Circulation and Return

Water circulation, which is essential for SPS, is done using thefollowing :

Water Circulation & Return
Equipment Output
2 sets of Tunze Stream 6000 2 x 7000 lit/hr
1st return pump Eheim 1262 (from sump to chiller to tank) 3400 lit/hr
2nd return pump Eheim 1262 (sump to tank) 3400 lit/hr
5 nos Maxijet 1200 5 x 1100 lit/hr

Filtration

Main filtration is through a DIY Single Beckett Protein Skimmerrun by an Iwaki MD 55 pump. Chamber diameter is 8 inches and heightof the chamber is 30 inches. I use small quantities of Rowaphos ina bag for Phosphate removal and changed monthly. GAC is used insmall quantities placed in a bag and changed weekly. I have aShallow Sand Bed in the main tank and Deep Sand Bed in one of thesump compartments.

Calcium and Alkalinity Supplement

Calcium and alkalinity supplement is done using a DIY DualChamber Calcium Reactor. Even with my high occupancy of SPScolonies in my tank, the Calcium Reactor is sufficient to fullysupport the tank and I rarely need to dose any additionalsupplement.

Chiller

Daeil Sun Cool � hp chiller run by the return pump Eheim 1262.The chiller is connected with 20mm PVC pipes from the pump in thesump and to the return into the tank. Temperature is set at 27 C. Irun a second standby chiller Daeil Fish-Cooler � hp as backup tothe main chiller set at a slightly higher temperature. This standbychiller is run using a separate loop (Eheim 1250) to cater forpossible pump failure to the main chiller.

Maintenance and Husbandry

I do 5% water change every week using distilled water and TropicMarine Pro-Reef salts. The skimmer collection cup is cleaned everyweek. The tank glass is cleaned daily with cleaning magnets. I dowater test every week using Salifert Test Kits. All top up waterusing distilled water is dripped with Kalkwasser every 2 to 3 days.I stopped dosing additional supplements for 5 months but recentlystarted dosing again.

Tropic Marine Lugol’s Solution 1 drop daily
Salifert Amino Acids 5 ml daily
Seachem Strontium 1 tsp daily
Fishes Mysis shrimp and pellets Once @ 2 days

Acknowledgements

I would especially thank my wife, Serina, for all her patienceto put up with this hobby of mine; as well as my 2 kids, Megan andTristan, who constantly amaze me with their newfound knowledge onmarine aquaria. They are the ones who started me on the hobby,which has since evolved into a daily conversation topic on thedinner table.

Many thanks also to the fellow reefers in Singapore who havehelped in one way or another to make this a truly fascinating hobbyfor me. You are a great bunch of guys.
