My 90-Gallon Reef Aquarium - Equipment

Overview Equipment Livestock Snapshot History

July 21, 2011


Filtration:

Primary filtration was initially provided by an Octopus NeedleWheel 150 Skimmer, but I later upgraded that to a Super Reef Octopus 2000 Internal Skimmer and observed a noticeable improvement. When first starting the setup, I had hoped that the large refugium would allow me to use an under-sized skimmer and minimize the disturbance to any plankton in the water column. However, cultivating and observing the benefits of said plankton turned out to be much harder than I had initially anticipated and after eventurally removing the last of my gorgonians, I decided to go with a more conventional approach and utilize a more appropriately-sized skimmer.

The SRO2000 is actually a little smaller, despite it's better performance.

I also started off using a Kent Marine PhosReactor to run carbon, but quickly replaced it with a Two Little Fishies PhosBan 150. I did this because I found it cumbersome and frustrating to change out carbon in the PhosReactor, due to its poor lid design. However, I eventually upgraded to the significantly larger Vertex UF-15 Media Reactor, which incidentally came with a much finer sponge - allowing me to upgrade to the much smaller ROX 0.8 carbon.

Source Water Filtration:

I started off with a 5-Stage 100 GPD RO-DI setup from www.MelevsReef.com. However, I eventually found this system too inefficient and slow for my needs. It produced roughly three times as much waste-water as filtered-water. Eventually, I modified the setup, adding a second RO filter to increase both the efficiency and speed at which I could produce filtered water. I also added some water pressure gauges, so I could more easily tell when to replace any filters.

Water Flow:

I started the system off with relatively weak water flow and then constantly improved it over time. Initially I had just two Hydor Korlia #3's (at 850 GPH each) in the display and a single Hydor Koralia #2 (at 600 GPH) in the refugium. For turn-over, I had just a single Danner Supreme Mag-5 (at 500 GPH) which, for the record, was a comparatively loud pump. By the time I shut down the system, I had increased water flow to three Hydor Koralia #3's and a CoralVue High Seas 201B (at 1,500 GPH) in the display and two Hydor Koralia #3's in the refugium. I had also decreased the noise of my setup by swapping out the Mag-5 for a Maxijet-1800 (at 450 GPH) and increased turn-over by adding a Maxijet-3000 (800 GPH) which returned water to the display tank via the chiller. Additionally, I added a Maxijet-1200 (300 GPH) which returned water to the display tank via the media reactor.

Lighting:

Lighting was another area that I started off weak with and then constantly improved on. The display tank was initially lit by a Sunlight Supply Tek 48" 4x54 watt T5 fixture, but I later upgraded that to a Aquactinics 48" 5x54 watt T5 fixture with active cooling. The Aquactinics light was considerably brighter and the active cooling allowed the bulbs to last longer. The refugium started off with a Coralife Aqualight 12" 2x18 watt Power Compact fixture that would only light up a small portion of it. I later replaced that with a Current USA Nova Extreme 24" 2x24 watt T5 fixture that would lit up about half the tank. Finally, after accidentally dropping that fixture into the water, I settled on a Current USA Nova Extreme 48" 2x54 watt T5 fixture that lit up the entire refugium. I also decided to use reddish bulbs (1x Giesemann Midday and 1x Giesemann Aqua Flora), to counter the bluish look of the display tank (2x Giesemann Aqua Blue and 3x Giesemann Actinic+).

I also later added an R2 Solutions 48" LED fixture with 24 LEDs to serve as a moon-light. The fixture was much too bright and I had to dial it down to 10% with the proprietary R2 controller I bought with it. Unfortunately this fixture came with no mounting legs, so I had to improvise by bending and painting some metal strips to serve the purpose.

Heating & Cooling:

Temperature control was initially provided by two Ebo Jager 250 watt heaters. I had initially thought a chiller would not be necessary, but after watching my system temperature climb to 84F in the summer months, I eventually purchased a TECO 1/3 HP chiller with a built-in 400 watt heater. This meant I could remove my Ebo Jager heaters. Unfortunately, I hadn't really planned for a chiller when laying out my system and the only feasable location for it proved a little awkward.

Evaporation Compensation:

Right from the start I utilized an www.AutoTopOff.com Sump Mount Double Switch controller from a previous setup and it never gave me any trouble. I never actually needed the second safey switch as the primary never failed. I eventually replaced the 18-gallon plastic container that I first used as a reservoir with a custom-built 18-gallon acrylic container that had almost half the front-print. This was very important because the reservoir took up space behind my setup. I also eventually started dosing kalk into the reservoir to help with low pH problems introduced by the calcium reactor.

Calcium Reactor:

I purchased a Single-Chamber Calcium Reactor setup from www.reeftek.com a couple of months into the system and had to wait even longer before I could set it up. I purchased:

My initial calcium reactor purchase.

Among all of this equipment, both of the Reef Fanatic products gave me trouble. The pH Controller had an electronics failure after two years (out of warranty), and I had to purchase another (although I did get 10% off). The CO2 regulator began failing after a few weeks (staying in the off position), and the warranty process took so long that I purchased an www.AquariumPlants.com Electronic CO2 Regulator in the meantime, which ultimately served me much better. When my replacement Reef Fanatic CO2 Regulator eventually arrived, I ended up selling it.

Monitoring Equipment:

I utilized three American Marine Pinpoint monitors for the setup: a pH monitor, a salinity monitor, and a temperature monitor (with four remote sensors). I never had any issues with these monitors. I did eventually learn to clean my pH probe in vinegar overnight before calibrating it, whenever it needed re-calibration. When my Reef Fanatic pH Controller suffered an electronics failure, I kept it around as a secondary pH monitor.
