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.
Name: Jamison Hensley
Location: Layton, UT
Occupation: Investment Advisor Rep
How long have you been in the hobby? 16 months
How long have you been a member of the club? 1 year
How did you hear about the WMAS? I used to frequent
reefcentral.com and a fellow WMAS member enlightened me.
2) Describe your tank. Acrylic or glass? Size in dimensions and
gallons. How long has it been set up?
Acrylic / Glass: All glass
Size in gallons: 120
Dimensions: 2 X 2 X 4
Age: (how long has the system been running) Since January
3) Describe your lighting system, including your photo-period.
Add what you would change if you could.
I have two 250 Watt 10k metal halides and two VHO actinics. My
actinics are on from 8am to 9pm
and my halides run from noon to 8pm. If I had it to do over again,
since I like LPS and softies and
since my corals seem to bleach out a little, I would likely go with
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 a crushed coral sand bed 4 inches deep, complimented by 140
lbs of Fijian live rock. I have an ASM G2 skimmer that I run
constantly. I have a 40 gallon sump with a small built-in refugium,
with lights on 24/7 with a 2 inch sand bed and various macro algaes.
I have one fixed return and one Sea swirl powered by an Iwaki 40
which pushes 2400 gph. I supplement the water flow with a small
submersible pump at 320 gph. My clean up crew consists of a variety
of about 50 hermits, 30 snails, an emerald crab and a green brittle
5) What are your maintenance techniques? Include water change
I do a bi-monthly 20% water change with Instant ocean salt and RO/DI
water. I clean my skimmer every ten days and clean the glass once
every four days. I harvest macro algae, Sargassum kelp and pesky
nuisance algaes every couple of weeks.
6) What additives do you use? Kalkwasser, Strontium, Molybdenum,
Iodine, Magnesium, Other
I dose Kalkwasser to replenish a healthy balance of Calcium and
alkalinity. When one or the other gets out of whack, I use Kent
Superbuffer for alkalinity and Prestone Driveway Heat for calcium. I
occasionally dose iodine and strontium.
7) Describe your feeding philosophy. Include your schedule, and
what you prefer to feed your system?
The remaining fish in my tank are quite opportunistic in feeding and
fend pretty well for themselves. I do feed about once every 3 days
with frozen brine and Nori. I target feed my BTA with krill and my
corals with Cyclopeeze and phytoplankton.
8) DIY ie, Calcium reactor, stand / hood, skimmer, sump, ect. Any
Do-it-yourself items of interest? Web-sites that you may have
I once attached a hang-on desk fan in my hood all by myself. I am
not a DIY-er, though I do plan to build a closed loop with Shane
Heil in the near future.
9) Stand and Canopy
Special Characteristics: Custom made
10) Items of interest: Favorite or unusual Fish, coral, or
Favorite Fish: Juvenile Imperator Angel
Favorite Coral: Pink Bird’s Nest
Favorite Polyps: Super Green Star polyps
Favorite Crab: Boxer or Pom pom crab
Favorite Worm: Coco worm
11) Can you include a table showing your elemental levels of Ca+,
alkalinity, S.G., temperature, pH and other interesting testables?
Salinity – 1.025 sg
pH – 8.2
Alkalinity – 10 dkh
Calcium – 400 ppm
Ammonia, Nitrite, Nitrate – 0, 0, 0. (as far as I can tell)
Temperature – 78 degrees
12) What experiences and challenges have you had with the tank?
Any lessons learned? Is there anything you do differently than
others (or differently than previously)? If so, why?
Where do I start? I am the poster child for one of those “Total
Makeover” aquarium shows. I have battled Cyanobacteria, hair algae
and now a red algae that looks similar to Bryopsis. I’ve lost my
share of expensive corals and fish as well. What I’ve learned, is
this hobby is totally worth it. I honestly learn something new every
day. If I were to start over again, I would have made a bigger
refugium, added more water flow, and bought a lot of high quality
used materials. I also would have joined the club about 3 months
before buying a tank. WMAS is awesome!!! I figure I’ve got a couple
decades to make improvements on this tank to learn as much as I can
before I do this all over again.
