Salty Q&A: Can Powerheads Be Concealed in Rockwork?

Ensuring proper flow in your aquarium should be the number one priority, then aestheticsQuestionI have a new 60-gallon reef tank, and I’m using two powerheads to provide water circulation. One is mounted in the upper right-hand corner of the tank near the back and the other is in the lower left-hand corner near the front. My problem is, while the powerheads are providing good water flow, I hate the look of them. To my eye, they stand out like a sore thumb, and I want my tank to look as naturalistic as possible. Is there any reason I can’t hide them in the rocks?” – Submitted by Amir Answer Thanks for your question, Amir. It is possible to conceal powerheads among the rockwork in a reef system, but before attempting to do so, you’ll need to consider each of the following important points: Proper flow trumps aesthetics Good water circulation is absolutely essential in a reef system, so any aesthetic consideration with respect to powerheads should come in a very distant second to the flow they provide. Keep in mind that hiding powerheads in rockwork can easily limit their output if you’re not careful in their placement. If you’re unable to achieve the desired water movement with the powerheads tucked away behind rocks, it’s better to leave them out in the open.

The Deep Dive on Reef Aquarium Lighting, Part 2: Lighting Technologies

I get asked fairly often what light is the best light. Unfortunately, there is no right answer. First off, there is the difference in aesthetics. That is a purely subjective decision that only hobbyists can make for themselves. Most of the time hobbyists gravitate towards the blue end of the spectrum because it is very flattering to corals that fluoresce brightly.In terms of coral biology, the type of lighting that will work the best for your tank will depend a great deal on what animals you intend to keep. As I mentioned in Part 1, corals will adapt to lighting by regulating their zooxanthellae, so most coral will grow under any of these lighting technologies. Having said that, it is also entirely possible to have some corals take on a desirable appearance while other corals become less attractive under the same light. Such is the price to be paid for a mixed reef tank

The Deep Dive on Reef Aquarium Lighting, Part 1: Zooxanthellae, Color Temperature, and Light Intensity

LEDs continue to gain a loyal following as a capable reef lighting technologyLighting is important because it directly affects how we visually enjoy the hobby and, more importantly, the vast majority of the corals in our tanks are photosynthetic. In this two-part article, we will first cover some of the basics of the light itself and then discuss the various lighting technologies people use to light their reefs. Coral and zooxanthellaeCoral as we know it is a symbiotic relationship between the coral animal and dinoflagellates called zooxanthellae. Zooxanthellae live in the tissue of the coral and are like algae in that they contain chlorophyll for photosynthesis. The byproducts of photosynthesis are things like simple sugars that the coral hosts can use as an energy source. It is for this reason that coral are often described to the layperson as having traits of both plants and animals. The color of zooxanthellae is varying degrees of brown. However, there are over 80 known varieties of zooxanthellae

Ecotech Marine Announces Radion Gen 4 LED Fixtures – Part 1

The new Ecotech models include the XR30wG4, G4PRO, and XR15wG4PRO and Ecotech expects to begin shipping orders later this month. The Radion G4 features a whole LED new cluster along with a new lens design. The re-balancing of proven colors combined with the addition of warm white and violet takes color rendition for your corals to the next level. Reconfiguration of the clusters compliments the all-new HEI lenses to deliver balanced color mixing better than ever before. The HEI lenses on the G4 deliver more usable light area. This is accomplished by spreading light that would normally create an area of high PAR directly under the LED fixture and redirecting it to a significantly wider optimal area of intensity for

Royal Exclusiv Dreambox Review – A Year Later

It has been nearly a year since I reviewed my Royal Exclusiv Dreambox and I wanted to provide an updated review to pass along some new insights and observations.  I had been using my Dreambox for about a month and a half when I did the first review so at that point my system was brand new. As a reminder, the sump is 74 US gallons and measures 59″L x 23-1/2″W x 13-3/4″T. Along with the sump I purchased a Bubble King Double Cone 250 skimmer, which included a RD3 Speedy pump, two Red Dragon 3 Speedy return pumps and two Royal Exclusiv Media Reactors, one with a 2L capacity and the other with a 5L capacity. My overall impression of the sump has not changed. You get what you
