What to Consider when Converting a Fish-only Tank to a Reef System

Evaluating your fish only aquarium and equipment is important before turning it into a reef“Caribbean Chris” and I are very frequently asked what it takes to convert a fish-only marine aquarium to a reef system containing corals and other sessile invertebrates. Can you just go ahead and add the invertebrates? Can you modify the existing system to suit the corals, or do you have to start the whole thing from scratch with a new tank and equipment? What has to change with respect to water conditions? Hopefully, the following points/suggestions will help address these and various other questions marine aquarium hobbyists often have when contemplating the transition from fish-only (or fish-only-with-live-rock) to reef:Pick a direction and do your homework Before making any new purchases or modifications to your existing aquarium, it’s important to pin down the type of reef system you want to keep. Are you primarily interested in soft corals?

Reef Threads Podcast #213


Palys are beautiful but palytoxin is dangerous. Use care when fragging or cleaning around palys.

Palytoxin leads off our list of topics this week. We also discuss, DJ power strips, Bill Wann’s 20,000-gal. reef, tackling Crown of Thorns starfish, used tanks, feeding nori, and chaetomorpha. Download the podcast here, or subscribe to our podcasts at iTunes. Also, follow us on Twitter at reefthreads.—Gary and Christine

Mr. Saltwater Tank’s 206 Gallon V.I.P. Build

Building a saltwater tank is one of my favorite things todo. I enjoy the client interactions, the planning, the challenges and I REALLY enjoy seeing the finished product. It never hurts when the tank is thriving as well.

Review: Maxspect XF150 Gyre Generator

Following on from our recent unboxing review in which we covered the basics of this unit, we’ve now had the XF150 running on our test tank for a few weeks so we thought we’d share out observations of this product in a full operational review. We’ve also been monitoring discussions on various forums with interest and we’ll aim to specifically discus some of the points raised with our own direct experience. Firstly, the XF150 is easy to install but it’s worth familiarising yourself fully with the operation of the device before sticking it straight in the tank. Although the unit comes in a single piece you will need to reassemble it if you are wanting to use it for anything other than constant one way gyre generation as the different rotors and cages will need to be fitted. It’s certainly worth running through this process anyway actually as being familiar with the principle behind the equipment’s operation will likely mean you get more out of it

The LTR Rainbow Incinerator Paly is a Knockout

Being that it is Friday and Christmas is so so close, we decided to relax a bit and enjoy the view. So, we are going to make today all about some awesome corals we recently spotted on the web. First up is the Rainbow Incinerator paly from Love The Reef. This awesome polyp symbolizes all that is awesome with these corals, sporting intense colors that would make any hobbyist stop and drool for a moment or two. They sport long skirts that have a striped pattern, along with a vibrant swathe of colors on its oral disc.

5 Signs of Inadequate Water Movement in Reef Aquariums

Proper water circulation is one of many elements that are key to maintaining a healthy reef system. While there’s no such thing as a one-size-fits-all water-flow scheme (you really have to tailor the flow to the unique needs of the invertebrates you keep), there are certain signs that will tip you off to inadequate circulation. Among them: 1) Detritus buildup in “dead spots” Some settling of detritus is unavoidable in a reef system, but excessive buildup tends to occur in tanks with inadequate water movement or “dead spots”—specific areas in the tank with poor to nonexistent flow. A good level of water movement will keep most particulate matter in suspension long enough to be captured by mechanical filtration media (socks, sponges, etc.), so this is a sign that you need to either boost the overall flow in the tank, by adding more or stronger sources (e.g. powerheads), or redirect existing water-flow sources to greater effect. 2) Corals fail to expand When coral specimens remain in a prolonged contracted state—with their tissues/polyps withdrawn—one possible explanation is inadequate water movement. Now, many different environmental factors can cause this behavior, so failure to expand is by no means diagnostic, but that symptom coupled with others listed here may be a good indicator that better circulation is in order. 3) Leather corals have trouble shedding Along very similar lines, if your livestock includes leather corals (e.g., Sarcophyton and Sinularia spp.), which occasionally go through a natural process of contracting their polyps, developing a waxy coating over their surface, and then eventually sloughing off this layer, inadequate water flow may make it difficult for them to shed.

ORA Hector’s Goby is the Latest Conquest of Captive Breeding

No sooner than we wrap up our coverage of all of ORA’s 2014 captive bred fish and aquacultured frags, the famed fish breeders announce one more entry for the year. Yesterday, they revealed tha they had bred the Hector’s Goby (Koumansetta hectori), a nifty little fish that is as strikingly beautiful as it is peaceful. This tiny fish measures just 2″ long at its maximum size, and it spends a majority of the day hovering hear the rocks while grazing on various types of algae. Thought to be the first time this fish has ever been captive-bred, ORA had some difficulty getting this fish to market, so to speak. This was due in part to the fish’s extremely tiny size, unreliable spawning amongst broodstock individuals, relatively long larval stages, and overall fragile larvae. Thankfully, ORA’s experience with the Priolepis genus translated flawlessly to the Hector’s Goby and they were eventually able to overcome those barriers.

Review: EcoTech RMS (Radion Mounting System)

Having already taken a look at EcoTechs gorgeous Radion XR15w Pro LED light in our recent unboxing review, we now turn our attention to their much-anticipated RMS (Radion Mounting System) which ties-in beautifully with the Radion Pro range and allows these lights to be elegantly suspended above even the most tricky of systems. As ever, the kit (XR15 version in our case) comes effectively packaged and all the parts are present and correct on initial inspection. After a quick skim of the simple instructions it obvious that we aren’t going to need a degree in rocket science to assemble this piece of kit, which is great. We are immediately and pleasantly surprised that some of the components here are metal, indeed the whole thing feels reassuringly heavy-duty compared to other brackets we’ve handled in the past. Somehow, the RMS still manages to look sleek and minimal though and it’s also nice to have thoughtful design features like integral cord management included. Overall the bracket also allows for a good deal of flexibility with the light able to slide back and to, or to be rotated on the X bracket (although this is primarily of use with the XR30)
