Hi guys, I hope this is the right place to post this question, but may I know what went wrong with my recent purchase? What happened was that I bought 2 red firefishes recently. When I got home, roughly 15/20 mins later, the fishes were already dead... Is there a particular way I'm supposed to request that the fishes be packed? Will two of them fight to the death in the short time they are in the bag? I did not see any torn fins though. Thanks.

Can start with soft corals (Zoas, Xenia, mushrooms etc). A lot hardier than hard corals. After a while can move on the LPS corals (hammer, bubble etc) As for live stock, IMO no damsels... I've become biased against keeping them after I had 2 for a month in a 2ft cube. They terrorise all new additions, too aggressive.

Do wash the hydrometer properly after use too. Otherwise the swing arm could collect salt deposits and the readings would be inaccurate in the long run.

May I know if anyone has seen a wartskin frogfish for sale? If so, do you mind sending me the price via PM? Thanks in advance.

Wow this is amazing. My mandarins have spawned multiple times but I just can't seem to catch the eggs even after I've turned the wave makers and return pump off. I can hardly see them...

I don't know if this is a good reefing practice or just a safety note but do set drip loops for all your electrical devices for your aquarium. Especially after some maintenance, there's a chance to forget to put the wires back in place for a drip loop.

Thanks for this thread! As for the super glue, I've used the dark green, light green and blue ones before for other projects. The blue ones are too watery, light green ones are good but they don't seem to be available anymore and the dark green ones work fine. Daiso also has those hard/used for arts and crafts plastic nettings for use in DIY-ing an algae scrubber.

Thanks for the generous offer anyway (:

Hey you strictly want dead rocks only? I've got some rocks but frankly, I don't know if they are dead or not. Pm me for more details if you're interested.

I'm pretty new too so I hope I can still help you as far as possible. I think there's a thread/post out there in SRC giving great advice to newbies venturing into marine aquaria. Please do search it up and read it thoroughly. Helps a ton. I would suggest setting a budget and planning out what you intend to keep. Or at least a rough idea of what your set up is to look like. Say a FOWLR (fish only with live rock) or a reef tank. Generally the bigger, the more stable the parameters and allow for a greater margin of error. Bigger tanks would also afford you the flexibility to keep more varieties of fish. Smaller tanks are easier to set up, equipment is cheaper (less initial investment for the beginner reefer) and are also probably easier to clean. Tank: If space allows, go for a tank with a sump. Increasing the total volume of water in your system, generally more stable. A sump would also allow you to dose your additives and hide your equipment away from viewing. As for the glass, depending on your tank's dimensions. The bigger the tank, the thicker the glass. Do note that tanks that are used to house marine aquaria have to be thicker than their freshwater counterparts due to the density of saltwater. You could also consider crystal glass if the greenish tint bothers you. Other equipment: Skimmers, Lights, Chillers etc have been discussed at great lengths all over the forum. Just do a simple search and everything turns up (: With particular notice to the chiller/heater: Heaters, nope. I've yet to see anyone use a heater in a reef tank in Singapore. (Im assuming you're local?) Chiller, not necessary unless you're keeping corals and cold water creatures. That being said, I heard that having cooler waters helps to slow down the metabolism of fish and contribute to a longer lifespan (: Hope that helps (:

Correct me if I'm wrong but I think there are a few LED drivers for sale over at the pasar malam section. Could give them a go, if by a stretch, you're considering DIY LED sets.

IOS - Internal Overflow Sump. (Correct me if I'm wrong but I remember reading this somewhere) If I were to hazard a guess based on your description, I'm inclined to believe that your tank has an IOS

Could consider RSM 130D.

Cool, nice tank. I started out wanting to keep a nano. But I decided to go a little bigger because I felt that parameters are easier to be kept stable in a bigger tank. May I know how much and how often do you change your water? Thanks.

If you're referring to aragonite (light coloured, whitish brown sand), then it could serve as a buffer too.

I've seen people keep shrimps or hermit crabs in their nano marine tanks. I'm not too sure if that's a good idea though. Just a suggestion. Do correct me if I'm wrong.

DIY cooling system? With a fridge? ._. If you're interested, check out auto top off systems to help you cope with your evaporation if you're gonna use fans as a DIY cooling option (:

You could drop me a PM if you're interested in DIY-ing your overflow in the event that you're interested in a sump. I can pass you the plan I'm currently using for my overflow. PVC pipes btw.

Hey, the lighting systems more commonly used in the hobby are t5s, metal halides and LEDs. With regard to wattage, it really depends what type of corals you are looking to keep. Most soft corals (e.g; mushrooms) should do fine in dimmer light while SPS corals are likely to require much brighter lights. Then there are also Non-photosynthetic corals (e.g; sun corals). So really, it depends on the corals you intend to keep. If you're okay with doing top ups every day then using a fan to cool the tank via evaporative cooling should suffice. However, do note that its very troublesome and also may cause your parameters to fluctuate beyond the threshold of the corals should you forget to top up. With a fan, you're looking at a drop of roughly 2 degrees celsius below room temperature. Whether a chiller is a necessity is once again, dependent on your target livestock. Most zoas and mushrooms should be okay at 28-29 degrees but SPS corals may not grow well and/or exhibit good coloration. So really, it depends on the corals you intend to keep.

Hey, I don't know if its the same thing but I used a dymax air driven skimmer too. I used a cheapo air pump with one of those 2 bucks sander wooden air stones it actually. What I found that you had to do was to give the skimmer a while to break in while monitoring the bubbles. Give it some time with small adjustments each time should help in my opinion.

I just started a marine tank a few months back. From my limited experience: I cycled my tank by burying market prawn in the sand, added some live rocks and monitored the parameters after a while. The ammonia would spike first and you would know that your cycling is complete after ammonia is 0 and only nitrates are present. I used saltwater from a fellow reefer's tank to start the cycling (Thanks Saeight!) From there, I stocked the tank with common clownfish and then mushroom corals a week or so down the road. As far as I know, a fan should be sufficient to keep the temperature between 28/29 degrees although the evaporation rate may cause the water parameters of a nano tank to fluctuate quite a bit. You could try auto top off systems. Sometimes there are a couple for sale around the pasar malam section. I DIY-ed my own for about 15 bucks or so (drop a PM if you're interested in making one. Its pretty easy). Chillers are expensive but they definitely help to keep the temperature of the water more constant.

As far as I know, not all gobies are as active in cleaning/sifting the sand. I've never seen my yellow watchman goby sift sand but I've seen twin spot gobies sift sand at ah beng. I've heard that sand sifting gobies are not suitable for small/new tanks because of the availability of sufficient food.

Sorry but may I know how do I go about doing that? Their mouths are at the bottom right? So i have to pluck it off the rock and flip it upside down to feed it? :/ Thanks.

Hi, I'm currently looking for an LED light set for my RSM 130. Either retrofit light sets by ecoxotic/Steve's LEDs or any custom LEDs would do too. I'm also considering used DIY light sets and modding them to fit the RSM's hood. Do drop me a PM if any of the above are available. Thanks a lot in advance (:
