  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

  9. 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

  13. 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

  14. 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

  15. 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.

  16. 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.

  18. 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

  20. 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

  21. 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

  24. 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.

  25. Just a small update, thanks for the comments. I recently tried using acropower. My corals colours have improved, there is a slight reduction in phosphate levels though my nitrates are still undetectable. There also improved in growth but at the same time increase in algae which drove my phosphate lower due to available nitrates. It probably take some time for the phos to bottom out. Felt like I found a cure. I believe this will only work for tank that looking to increase nitrate and has undetectable nitrates and detectable phosphate.

  34. As I had great experience working with CRA, I went back to look for Dan, whose company has been rebranded as Tank Culture, to build my tank. Here are the 2D drawings of the tank/sump layout, inclusive of the frag/lps tank and quarantine tank housed in the Fish room. The 4.5ft frag/lps tank is connected to the main display and sump and both tanks are powered by 2 separate return pumps (always preferred to make the insurance if one fails). The Quarantine Tank is a separate IOS tank housed below the frag/lps tank. You might be wondering why I called it a LPS tank. It’s probably because I

  37. You said 'RO' does that mean you dont have DI resin?? I get 0 TDS all the time from a simple 5 micron sediment filter, two carbon blocks, a basic 75gpd RO membrane and some mixed bed DI resin. I tend to work backwards when I have an RODI issue (The sediment and carbon filter tend to help the RO membrane last longer. The membrane does all the heavy lifting, hence the reason to work backwards). So, firstly check your DI resin is fully packed well into the DI canister, as you could be reading some creep if not. If all packed in, does it need replacing?? If not and the resin is ok, next bet is y

  45. Nice write up! It appears that ciliates are associated with many coral diseases. But the question is, are they the cause of the disease, or are they just proliferates when the tissues become necrotic. It could also be the case of increased pathogenic bacteria population at the disease coral, which provides food for these bacteriaphagic ciliates Great start for more discovery!

  47. 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/
