    Welcome back!

    Looking forward to see more photos and videos of the new peninsula!!

    Good to be back after a long hiatus! Following along your tank thread closely too.

    We really do struggle with "real estate" but Singaporeans make the best out of what we have! Haha

  2. Figured that I have an extra space at the right of my tank and decided to add in another tank on the right. Can be used for frags or dedicated species only.

    RMS did a detailed drawing of the tank built. Can tell from the drawing that they put pride in their work. :wub:

    Natural sunlight….. but need to be more hardworking to clean Algae…. You have problem viewing the tank in the day time too due to the diffused sunlight .

    @Reefhappy thought about the same algae issue as well. Yes, need to put in more elbow grease to maintain the tank. 

  4. After rounds of talks and enquiring with various LFSs.

    Decided to settle and entrust my project to ReefMarketSG as they are able to oversee the full tank setup (tank built, piping, equipment, compressor, planning, scheduling and coordinating)

    My project was no easy task as there are many obstacles and factors to consider when building the tank on the balcony.

    • Renovation was already done by the ex-owner of the property, unable to run compressor piping to the service yard.
    • Specific and accurate measurements were required due to the sizing of the balcony
    • Professional Engineers and MCST approval are needed to measure the weight load of the tank sited on the balcony.
    • Balcony is one step lower than the living room floor, require measurements to ensure accessibility of the sump and its equipment
    • Balcony power point have to be calculated to be able to handle the electric load of the equipment

    Gotten the keys to my unit earlier this April, ReefMarketSG immediately arranged their representatives to take on-site measurements and plan out my tank.

    We settled on a 600L tank with the dimensions of 4 x 2.5 x 1.8. Was provided with a mock drawing to visualize the placement of the tank.

  5. Decommissioned my previous pride and joy a year ago as I was planning on shifting residence.

    Signed on the dotted lines early this year to purchase my new home and started planning on my tank setup.

    Decided to locate my tank in the balcony and started sourcing LFSs to take on my project.

    Did a rough mock up drawing of the tank :)

    Food for Thought

    Imagine you are a colony of super sun coral,  sitting in the shade along some reef slope or a cave. Since you don't have any zooxanthelle, you have to actively capture food from the surrounding to stay alive. So what kind of food would you likely eat? 

    IMG_20210901_232133.jpg.870b39d6f8a6b6faafc8e7ebe1a97dcf.jpg

    Looking at the size of the mouth of these dendrophyllia,  it's only natural to think that probably small pellet sized food is what they eat naturally, because they kind of fit right into the mount of the coral. Yet as I look closely at these animals, I realised that something doesn't add up. 

    For a wild colony of dendrophyllia, how likely is it for each individual polyps to have access to large and slow food, on a regular basis? 

    Nobody is target feeding these corals 365 days a year. Therefore I felt it is very unlikely that these NPS would demand large particles of food.

     

    Pico and Nanoplankton

    The ocean is awash with different planktons,  but when it comes to size and availability, there is a lot of difference.  Turns out that the smaller the size of the plankton,  the more abundant they are(Darcy,2014)

    It is then much more sensible for all these sessile predators to go after the most abundant of preys - pico and nanoplankton. These consists of bacteioplanktons,  dinoflagellate, diatoms and a variety of micro algae. The size of these particles ranges from 0.2-20 um (while in contrast, reef roid has a particle size of 150-300 um).

    Having looked around for some studies to confirm or disapprove my guess,  I came across several papers. In one study(Leal, 2014),  the author used molecular markers to test if coral species takes up microalgae.  In another (Houlbrèque, 2004) the authors examine the importance of planktonic prey for corals.  They were able to show that the corals do obtain significant organic carbon and proteins from these planktonic food. 

     

    Implications? 

    Finding the correct food source for corals (regardless of zooxanthelle) is an area for progress to be made. No doubt the commercially available coral supplements are getting better. But could there be some "holy grail" food that we can supply to our aquarium? 

    In my opinion, while ground up plankton and krill may have a strong odour, and elicit feeding response, they may not provide the optimum size and nutrient profile for the corals.

    That's why I embark on a journey to search for better coral food.  (Tbc)
