I have been in the reefing hobby since 1996 close to 22 yrs. I've had fresh water aquariums since I was 7 yrs old, so I'm considered an old hand and pretty much a lifer. No breaks by the way, always had a tank running. A lot has changed since I started, the only information available were found in books, Marine Atlas was my bible. Now the information highway we call the internet, has so much information makes this hobby a whole lot easier.

This tank has been up and running since 2013 upgraded from a 185g which I had for 9yrs prior. I've had about 3 reboots due to too much growth, which is a good problem and keeps my love of this hobby interesting and what I consider a piece of art that's always changing.

Water Circulation and Flow Summary and Objectives:

I never measured turnover rate, but its maybe close to 10x the water volume. What I consider the 2nd most important element second to water quality is flow and I have lots of it and I like it chaotic and provide great exercise for my fish. I advise it all the time, to always get enough flow especially in a SPS dominant tank.


Water Parameters:
  • Temp: 80
  • pH: 7.9-8.4
  • Specific gravity: 1.026
  • NO3: never check
  • Ca: 450
  • Alk: 7
  • Mg: 1400
  • PO4: .38
  • Ammonia and nitrites: never check

Lighting Summary and Objectives:

Lighting is the 3rd most important element behind water quality and flow in my book. T5 is my choice for lighting, its time tested and proven. Also I like my display on the daylight side, blues are on only briefly in the first hour and 1 hour before all lights are off. Change out the bulbs once a year on Black Friday when they're on sale, also keeps me on track when I need to change them.


  • Display tank: Leds come on at 10am to 10pm, First set of 4 T5 come on at 12pm to 8pm, 2nd set of 4 T5 come on at 1:30pm to 7:30pm
  • Grow-out tank: same as my main schedule.
  • Refugium: midnight to noon

Filtration and Water Quality Summary and Objectives:

Water Quality is the most important element in reef keeping. I use the EcoSystem Miracle Mud method, been using it since day 1. with a very efficient skimmer 24/7 is what works best for me and no filter socks. I change out 25lbs of miracle mud once a year. Love to keep dense Feather Caulerpa in my fuge, only trim when I need to. As far as testing, I don't chase numbers and don't test very often, only test alk once a month. Your eyes is the most important tester you can have, and they tell me when there is something wrong. I'm on schedule to do water changes every 2 weeks of about 50g but sometimes go up to 30 days. I never touch the DT, I change the water from the sump, which is plumbed to pump water out to my laundry sink and leave the DT untouched and all I turn off is the Main return pump and let the sump fill up to the highest it can go. Takes about 30 min from start to finish to do a water change.

Changing out the filters on the RODI system is on a calendar schedule.

Fish and Coral Feeding: I feed my fish 3-4 times a day, combination of pellets, seaweed and mixture of frozen foods.

Who was responsible for getting you into the hobby?

I was already in the aquarium hobby, with my planted Discus tanks, and every time I went to the LFS I always found myself in the salt water aisle, so it was inevitable.

How long have you been doing this?

Reefing 22 years


Who or what in the hobby most influences/inspires you?

Just the overall reef community inspire me, met some great friends through this hobby. What keeps me going is the challenge in keeping my little piece of the ocean in my family room. Also the support of my beautiful wife Joleen, who never questions me on any decisions I make with this hobby.

What are your future plans for improvement/upgrade of the tank?

Purchasing a 84" x 48" x 25" 436g Rimless from Crystal Dynamics Aquarium Mfg. from Oceanside Ca. Hope to have it running by the summer of 2018, so keep a lookout for my build thread.


Final Thoughts?

There has been a lot of changes since I started 22 years ago, And in my honest opinion the Art of Reef Keeping has fallen a bit, and I dont see many full blown reef tanks now a days. Alot of high end collectors with frag tanks. Which I think is fine, its just another part of the hobby. But I always pictured a reef tank with large colonies, and let the corals create the aquascape, and create a beautiful piece of art. I just want to see more of it, whether its a full blown 10g nano or a 500g behemoth.

What a fantastic way to start off the New Year!!!!

Your tank is a work of art.

The miracle mud surprised me, guess that goes to show how important a fuge is.

Nice to see T5 tanks, such great coloration.

C'mon! Show stopper! You just walked into the club with like the best lookin' girl in the place!

Seriously. Very nice job. The scape, the gear, the fish selection, the coral selection and color saturation, rendition..... you've got it all here. And in a stock Marineland tank to boot?!

Top dog of 2018!

Great tank indeed! What are those gorgeous yellow acro colonies? Was that picture taken without filters? They are amazing!

What T5 combo are you running on your ATI fixture?
I believe the yellow acro is the Pikachu...

RR Wolverine, and RR Pink Floyd. Don't believe I used a filter on that pic, I did use a filter on the WD top down pic.

Thanks Tom!, I still remember the day I went over to see your tank, which motivated me buy the 300g.
