  1. Starting a new thread journeying into the microscopic world of our reef tanks. Not all images are mine. But will also include filter/coral/wool samples that cross my path. Hopefully this thread will be a useful reference to shed light on issues we see in our tanks such as algae or even fish parasite issues. And to encourage discussion about the right treatment once we identify what it is under the microscope. To the naked eye, diatoms look similar to dinoflagellates but are actually very different under the microscope. The treatment path is also different. Applying the wrong fix will

  2. 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

  3. One thing I love about this hobby is the constant ability to learn something new. However, there are also occasions where it is worth learning something old. Techniques that reefers used historically but are in dire need of resurrection, forgotten heroes (or heroines) so to speak. As such I wanted to share a few topics on reefing that I hope you find useful. So let's start the ball rolling with the first forgotten hero... Sulphur Denitrifiers. For the life of me I just don't understand why Sulphur Reactors are not more popular after all they are possibly one of the easiest "set and

  6. Normally I place another frag plug/rock under the mushroom and hoping it will grow on it. Sometimes it eventually splits, I'm guessing this is probably due to the uneven surfaces.

  7. Cause related to DOC may be hard to prove without controlled experiments & proper equipment. What I have is anecdotal data which may not be able to demonstrate root cause or nail down to the factors affecting the result. Bacteria is a new topic & am keen to explore more. I did notice 2 incidences of massive SPS RTN (really overnight) several days apart. A slimy cloud was observed just above the rocks. Sections of various SPS colonies in contact with the slimy cloud had the flesh peel off overnight. Everything else above it was OK. In both incidences, the tank were fed with Ocean N

  8. I've started to journey into the microscopic world of the reef tank. Invested in a good microscope with a camera hooked up. Its great to be able to pinpoint issues and apply the correct fix. For example : Is this dinoflagellates or diatoms? What kind of algae is this? Or be able to identify various parasites. For a start, many have experienced brown jelly disease on hammer & torch corals. The common advise is to discard it immediately as the brown jelly can spread. Another common advise is to dip the coral with coral dip or with iodine to disinfect it. This post hopes to g

  12. Forgotten Heros Part 2: Diatom Filters Imagine if you will a filter that is so fine it can polish your saltwater removing even bacteria. That, my fellow reefers is a diatomaceous earth (aka Diatom) filter. Now, the funny thing about a diatom filter is that, well, it isn't a filter per se. [Huh??] It is actually a natural powder made form fossilised algea (diatoms). The powder is added to a filter to reduce the size of the pores of that filter and is equivalent of adding millions of microscopic 'bio balls'. These microscopic particles (which are actually fossilised diatom shells) contain

  13. The next big task would be to fill this tank up with salt water! By the way, forgot to mention that I wasted about 600litres of rodi water (which means much more actual water) doing a leak test for the tanks.. feel so bad for the save water movement, but having a leak would be far worse I supposed. Water change is one of the critical process to maintain a healthy reef tank and a lot of thought was devoted to keep this process as easy as possible.. Other than building an outlet for waste water, I also built an water inlet (complete with a basin) within the fish room. The RODI feeds from the w

  14. Renovation is underway! And the tank is delivered! By the way, I opt for a galvanized iron frame to allow full access (without pillar) to my sump. Probably doable if you opt for aluminum frame too. Well my carpenter keep telling me it’s challenging to build the carpentry for a hooded tank. Realised so as I see them trying to fit the suspended hood to the tank like a glove. The almost completed carpentry for the display tank. Looks pretty much like how I imagined it. The air vent is also designed to allow circulation without allowing light from the tank to be “exposed” on the exterior.

  15. Letting go of tank+sump+cabinet+hood for free. Tank has already been drained. Will probably need to clean up the tank and change out the rusty hinges and it will be good to use again. Tank was used for around 6/7 years. Custom made from Irwana with good quality cabinet wood structure, so I believe there’re still many more good years to go for the tank set. Taker to arrange for mover to dismantle and transport the tank/sump/cabinet. pictures as attached. PM if interested. Will dispose if no takers by 2 May.

  17. I have used the exact same chinese chiller in the picture above and also switched to hailea 28a few months after, ran both on my old 10 gallon nano. One thing I noticed was that the chinese chiller ran for longer periods of time as it took longer to reach the temperature set. Now I've upgraded to a 40 gallon and still continued using the same hailea chiller. TLDR; hailea is a great option if you do have plans to upgrade in near future

  19. It has been one month+ since using the Mastertronic. And about 3yrs+ with the Alkatronic. There has been queries from fellow reefers along the way. I'll share some pics & comments here. Let's start with Mastertronic. Configuration & setup : Mine is set up to run Ca, Mg, PO4 & NO3. While the Mastertronic is able to test Alkalinity (using Salifert test kit), I configured mine to skip alkalinity and continue to use Alkatronic to measure this parameter. Alkatronic uses its own proprietary reagent to measure the change of pH using a pH probe. Each bottle can last ~2500

  20. For $20, I have a sturdy 28L, 6mm glass, ATO reservoir (dimensions in cm 58 x 12 x48high). It has split glass cover/lids which have been drilled for cables and tubes. Could also used as a small refugium or if adventurous a mini display tank. Just $20. WhatsApp me on 88080763 or PM me here. Happy reefing. Sent from Singapore Reef Club mobile app

  23. There could be various reasons. But one likely one is that it is bleaching due to excessive light. Gonio generally prefer low light conditions. From the picture, it seems to be placed at a location that's bright enough for SPS/Monti. Perhaps its too bright. Would suggest to bring it to a more shaded spot.

  24. Hi, you are right, it may due to the tank is realtively new. Though the tank has detectable nitrates and phos, salinity wise also stable. But the fact that it started receding within hours and got worst overnight. And I shifted it to more established tank next morning, which may also make things worst. It didn't stop receding and probably a goner in day 4. It's a single head torch that spliting into 3 heads, so each day from one head spread to another head. But my thought was that it shouldn't rtn that fast consider the tank parameters are in range. If it's due to not enough nutrients, it shou

  33. The problem of colormetric tests is that it tends to be rather subjective. They are also rather dependent on ambient light conditions. I would not worry too much at this stage. Just let your tank take its pace to cycle. Do ghost feed a bit though. Because we not only want to build up nitrifying bacteria, we also want bacteria which help to decompose other organics.

  35. An RO membrane is considered the most important element of an RODI system. The sediment and carbon filters act as pre filters to reduce the amount of large moleculed contaminants entering and clogging the membrane. It is the membrane that does all the heavy lifting. Why the RO is so important is unlike the carbon blocks it works under pressure (hence good systems include a pump) and as such it literally strains virtually all unwanted impurities from the mains supply, allowing only 'pure' water molecules to pass through... so as long as you are happy having small molecule impurities, salts, hea

  36. Since it will take a while to cycle the tank, and I’m not gonna rush this critical process, my first task before any of the equipment is up, is to build the scape and kick start the cycling process. Even though I have yet to purchase most of the equipment. Learnt from previous experience that it is much easier to build a scape dry. I chose to use a combination of caribsea life rock (love the shapes) and my bleached/cured rocks from my previous tank. Started by building the first tier of the 6 foot rockscape. Here’s the final two island scape.. not the best shot and it looks like it’s full

  50. Went through the very dreaded task of rinsing the sulfur reactor last weekend. Saved up 3 buckets of tank water during water change to rinse the mulm off the sulfur beads. Nevertheless, the reactor needs to go through the cycling process again (hopefully shorter cycle) In the process, the ceramic shaft of the pump was found to be broken. Good thing a spare was available in my stash of spare parts. A good time after that to put up the hammock & relax. From Airmocks : https://www.airmocks.com/
