Hi, Future Tank of the month WMAS member! Thank you for allowing us to showcase your tank on our website. To assist you in your write up, we have compiled a list of things to consider:

1) Your name, location and occupation. Include how long you have been an aquarist, how long you have been a WMAS member and how you heard of our club.
Josh Zorn
Location: Riverton, Utah
student 9th grade
How long have you been in the hobby?
I have always had a tank. My parents got me my first tank when I was 3 and I started caring for it when I was 8. When I was 11 I got my first 30 gal SW tank and then progressed to a 55 gal. Now I am 14 and I have upgraded to a 210 gallon reef.
How long have you been a member of the club?
2 ½ years
How did you hear about the WMAS?
I found it searching on the web for fish stuff

2) Describe your tank. Acrylic or glass? Size in dimensions and gallons. How long has it been set up?
Acrylic / Glass:
Main-Glass Sump-acrylic
Size in gallons:
210 gal Main aquarium 70 gal sump
Main H 28” W 24” L 72” sump
Age: (how long has the system been running)
since Nov 2005, I did move everything over from my 2 yr old 55 gal reef.

3) Describe your lighting system, including your photo-period. Add what you would change if you could.

I have three 250 watt Aqua Medic HQI DE halides pattern for kelvins is
20,000K 14,000K 20,000K. I also have two 48” coralife 20,000K VHO’s. On the sump I have one plant light. The main lights are from

Halides 7:30AM - 10:00PM daily
VHO’s 7:00AM – 10:30PM daily

4) Describe your filtration system. Include: How deep is your sand bed, plenum, your skimmer size and model and how long you run it, your circulation pumps (how many and their size in gallons per hour), your sump/refugium including Reverse Daylight, biowheels and skilters, HOT systems, clean up crew.

I Have the average clean up crew consisting of snails, hermit crabs, shrimp, worms… My filtration system consits of Sponge and natural organisms and a ASM G4 Protein skimmer. I change that out when needed. My main pump is a Sequence Dart Barraccuda which feeds to 6 outlets four wich are lockline and two that are ¾” seaswirls. I also have three powerheads in the main tank one maxi jet 1200 and two that are Via Aqua powerhead 402

5) What are your maintenance techniques? Include water change schedule.

I do a 10% water change about once a week or every two weeks. I scrape the glass when needed. Clean bulbs, change skimmer. Other than that I let the biological bacteria and natural organisms take care of it.

6) What additives do you use? Kalkwasser, Strontium, Molybdenum, Iodine, Magnesium, Other
I use kent products. I add Calcium, Strontium, Molybdenum, Iodine, Magnesium, essential elements,

7) Describe your feeding philosophy. Include your schedule, and what you prefer to feed your system?

I have always used the same philosophy and I try to make it as natural as I can I feed three times daily. In the morning cyclopeez. Later around 5 I feed a mixture of flake and cyclopeez and at night I spot feed LPS and other carnivorous corals mysis and cyclopeez again. I figure if you feed small amounts often it can repeat and mimic how fish feed in their wild habitats.

8) DIY ie, Calcium reactor, stand / hood, skimmer, sump, ect. Any Do-it-yourself items of interest? Web-sites that you may have referenced?

I use Kent supplies. Calcium, strontium & molybdenum, Iodine, and essential elements. I dose once a week on the weekends. I turn my skimmer off for about 24 hours after I dose

9) Stand and Canopy
knotty alder
Dark cherry red
Special Characteristics:
I love the hood it is very easy access to a tank and that is something that is very important in a tank as big as this.

10) Items of interest: Favorite or unusual Fish, coral, or invertebrate

Favorite Fish:
all my Tangs I am a Tang freak.
Favorite Coral:
Mike palletta tort
Favorite Worm:
My feather duster embedded in brain coral
Favorite Clam:
my Teardrop Maxima

11) Can you include a table showing your elemental levels of Ca+, alkalinity, S.G., temperature, pH and other interesting testables?
Salinity: 1.0245 – 1.025 I test once a week with a Refractometer.
               Ammonia: 0
               Nitrate: 0
               Nitrite: 0
               pH: ~ 8.2 I don’t test very often
               Calcium: 450 – 500 ppm
I use Hagen products they seem to work best for me.
