  2. Hi guys, decomming my tank as i am shifting house soon. Corals are to go first before fishes and then equipments/tank. Basic tank parameters: kH 7.5 no3 2-5ppm p04 - 0.2ppm I have high nutrients and i feed alot, therefore colors are not at their best but still relatively good. I also have a flameback angel and it occasionally nips on the SPS, therefore there are not much PE on the sps now. Please refer to number below for pic of individual coral pieces, size stated are estimated. SPS: S1 - Golden Millepora colony 2.5 x 2.5" big- $50 S2 - Strawberry Shortcake acropora big colony 4 x 2.5" big- $150 S3 - Red millepora 3" tall- $40 S4- Sunset Millepora 2 x2" big- $40 S5 - Bali slimer dual branch 2"- $30 S6 - Strawberry shortcake mini colony multi-branch 2" - $40 S7 - Strawberry shortcake frag 1" fully encrusted- $20 S8 - Hot pink millepora 1.5" fully encrusted - $35 S9 - Pearl Berry Acropora 2" multibranch- $30 S10 - Blue green tenuis colony 4" - $30 S11 - Homewrecker acropora (bright yellow polyps) 3" tall- $60 S12 - WaltDisney acropora 2.5" multibranch- $40 S13 - Walt Disney acropora 2" fully encrusted- $30 S14 - tri-color stag colony 4-5" tall- $50 S15 - Red stag colony 2" fully encrusted- $30 S16 - Red body blue polyp acropora 1.5" fully encrusted- $30 S17 - Miyagi tort acro 3" fully encrusted- $40 S18 - True Optic Fibre Pocci 3.5" diameter ball shape- $45 S19 - Setosa montipora colony 3"x2"- $60 S20 - rainbow stag 2" fully encrusted- $45 S21 - blue dragon 2" - $20 S22 - blue dragon 2"- $30 S23 - Aussie deep blue tenuis colony 3x2" big colony- $120 S24 - purple bonsai mini colony - $30 S25 - Green tenuis - $20 LPS/other corals L1 - Golden hammer (2-3 heads with a baby head growing at the side) - $40 L2 - UFO Chalice colony (multiple eyes) - $120 L3 - Electric Blue Ultra maxima (shell alone about 3.5") with lots of yellow sponges growing at the side - $150 PLEASE READ Collect ONLY at woodlands, no reservations as there's too many to keep track of and too many flying aeroplane nowadays. If you are keen in taking many pieces i will allow reservation with deposit. Price are fixed but discounts will be given if taking multiple pieces. Whatsapp me at 910six393four, try not to PM me as i often miss it, prority goes to whoever is taking more so easier for me to clear. Thanks for reading, pics coming up next!

  6. A couple more pics of diatoms They are in fact beneficial and always present in a balanced tank system. According to Wikipedia, diatoms in the ocean generate 20% of the oxygen produced on the planet each year. Diatoms are a form of photosynthetic single cell phytoplankton. While some reefers hate it, here are some fun facts on diatoms Diatoms take up silicic acid from the water to form a silica shell (a form of glass). Sources of silicon : silica sand/quartz sand (from the beach), tap water, marine salt mix Diatom chloroplasts (i.e. plant cell organelles that convert light energy into chemical energy via the photosynthetic process) are yellowish brown due to the presence of photosynthetic pigments such as chlorophyll (green), beta carotene (orange), and fucoxanthin (orange) Cell walls made of silica (glass). Their exoskeleton are made of 2 halves that fit inside one another perfectly. The walls are called frustules and have 2 main shapes – longish shape (called Pennate) and disc/cylindrical shape called centric) Diatoms are beneficial – they can outcompete the growth of other types of algae. And prevent HAB (Harmful Algae Bloom) – green water, cyanobacteria bloom, dinoflagellates Copepods eat phytoplankton (including diatoms) which in turn feed the fish Note that once silicates are depleted, other forms of algae can appear. Hence a good balance is required. Silica are in fact critical for the reef aquarium. Normal levels are 0.02ppm - 2.9ppm. Marine organisms that use silica : Marine sponges (beneficial filter feeder) incorporate silicates in their structure. Some mollusks (snails) have radula (teeth) to scrape off algae from rocks/glass. These teeth contain substantial silica. And of course, diatoms - benefits mentioned above. Credit : Pic from https://socratic.org/ In any case, if diatoms are a bother, especially when silica levels are elevated beyond the normal levels mentioned earlier, consider the following : 'Export' the silicates by siphoning out the diatoms when they form. Don't just stir or turkey baster it off the rocks/sand bed Use aragonite sand instead of quartz/silica sand Avoid using tap water. ICP test of tap water at Bt Batok has 1.12ppm of silicon. Use a good RODI filter to prepare water for water change & top up Use resins such as Rowaphos (and probably other similar products). These remove plenty of phosphates but also some level of silicates.
