Review: Elos OsmoController Digital

Dealing with evaporation from a reef tank can be a real chore if you haven’t got a robust system in place and there’s also a pretty high element of risk involved if your chosen system isn’t up to scratch. For a start, it could fail to keep-up with demand (in which case a low water level could expose equipment and lead to a system failure), or at the other end of the scale, overfilling could make your tank literally ‘runneth-over’ (causing untold damage and recrimination). In either case your Salinity is also going to be ‘all over the place’ too, stressing livestock, possibly to death…. in short this is one area where cutting-costs can come back and ‘bite you on the bum’! Having started-off with the ‘religiously-trickling-in-a-jug-of-RO-every-day’ method back in the day, we’ve since been through a few different systems, each progressing in complexity. Our second system was a simple peri-pump on a timer which delivered Kalkwasser during the night (and which worked fine but couldn’t cope with seasonal fluctuations very well) and next we experimented with float switches… briefly

What Constitutes a Marine Biotope Aquarium?

A biotope can serve as inspiration for your aquarium, but what exactly is it?For today’s post, I’d like to take a slightly different tack than usual. By presenting my meandering thought process on the concept of marine biotope aquariums, I’m hoping to elicit some input from you, my fellow salties, on precisely how to define this term—or if we can even agree on a definition at all. The question, as I see it, is one of scope. If we assume a biotope tank is an attempt to replicate a specific natural marine habitat, then how narrowly should we define that? In other words, where does a generalized tank end and a biotope begin? Is it:A tank representing a particular ocean or sea? As regular salties know, all the livestock in “Caribbean Chris’s” tank is found only in the Caribbean Sea. In fact, Chris seems to regard the existence of other seas/oceans the same way one might the existence of Bigfoot or the Loch Ness Monster—with skepticism

Digital-Reefs Update – The Difference is Black and White

As usual it’s pretty difficult to find time to produce general updates on our test system as more often than not, on top of our ‘proper job’ and family commitments, we are frequently busy collecting, unboxing and reviewing new kit, rooting out interesting stories for the blog, or producing material for ourselves or our clients. To be honest a lot of our blog work hinges on regularly chasing companies for the latest info and let’s say some are more responsive than others! Sometimes it can get a little frustrating but we certainly appreciate having the fantastic spread of sponsors that we do… you can tell these companies are the best in the business by their willingness to ‘show off’ their products at a hobbyist level rather than adopting a secretive, isolated approach. Anyway, before we digress, let’s get back to the task in hand and take a look at the Black Tank which is our 100 UK gallon test bed system, now just over 2 years old. Well, overall the system is progressing nicely and many of our colonies are continuing to grow steadily and fill out the tank. Aesthetically we are pretty happy with the system as it is, but it’s certainly not a finished product by any means.

Early Success with a Halichoeres Wrasse!

Figure 1. Halichoeres melanurus egg on a 1 mm SedgewickRafter cell. Here at the Tropical Aquaculture Lab we’re very fortunate to have the opportunity to work in a field we’re truly passionate about. That passion inspires me to not only work on captive breeding of marine species here at work, but to also explore other fish by working from home. I’m pleased to announce that the first project I’ve taken on as an at-home aquaculturist resulted in the successful captive rearing of the melanurus wrasse, Halichoeres melanurus, using only cultured prey items. Although only a few fish were brought through metamorphosis, survival should be higher when larvae are raised in the controlled environment of a dedicated facility as opposed to the chaos of a household living room. I strongly believe this fish, and others in this genus, will have significant commercial potential. We now have broodstock at the Tropical Aquaculture Lab because of this early success. The work done so far will stand as strong supportive evidence to move forward with other wrasses as well.

EcoTech VorTech ‘QuietDrive’ Pumps Announced

Rumour and speculation have been rife over the last couple of weeks but now the embargo has finally been lifted, we can stop ‘keeping it quiet’ as it were, and bring you official details on the latest product development from our sponsor Ecotech Marine! We’ve studied the offical 16 page release at length so here are the key points. Building on the already award-winning VorTech pump line, the new MP10wQD, MP40wQD and MP60wQD offer claimed improvements in noise reduction, efficiency, flow and durability. Specifically, this next evolution of the VorTech range offers up to 90% noise reduction and up to 40% more output* while the line retains connectivity and offers a new gyre flow mode.

Decisions, Decisions: New SAIA Tool Can Help Stock Your Nano Reef

Focusing on nano tanks, AquarioScenario is a new tool from the SAIA. Along the lines of their existing FishSelector, this interface offers the aquarium hobbyist guidance on selecting organisms for stocking a tank in an ethical and sustainable way, while avoiding impulse buying. AquarioScenario also incorporates the SAIAs ‘Lists of Unsuitable and UnsustainableSpecies’, and ensures the combinations of marine life suggested are suitable and compatible, considering not only size, but also behaviour and needs of the species. So, if you are feeling overwhelmed with the many decisions to make and options to choose from when planning your small reef, AquarioScenario can assist by suggesting possible combinations of marine life for each tank size range, while still ensuring an interesting display.
