Specs Out For New Nano Koralia From Hydor

Hydor are a company who’s products we’ve used before and we have to say, we really like their approach. They are certainly always looking to bring new products to the aquarium market and strive to make reef-keeping easy. In terms of their flow pump range, although already offering some of the most compact and efficient models available, they continue to make their products smaller, reduce electricity consumption and increase water flow output.

The Digital Reefs Black Tank – Passing 18 Months.

IMG_2776webAs an update to the feature on our test tank in issue 43 of UltraMarine magazine way back in December 2013, we thought it was high time we put together another of our ‘black tank updates’ as the system has also recently passed the minor milestone of 18 months old.
