    Man, I have missed your updates. You must be pretty busy these days, the updates come so far apart!

  • Jeff says:

    Who build the stand and canopy, really like the work done there, looks great and extremely functional.

  • eric says:

    Hey Mark nice build, sweet tank, I can’t wait to see updates and thanks for sharing.

  • Mark H. says:

    Pretty sweet Mark, I almost gave up on you….
    But i know you are pretty busy and have to support a family.
    Can’t wait for part three.

  • No Part 3 Mark H…we’re moving…

    😀 (just kidding! I’m NOT moving for a long while!)

  • Jeff…the tank builder, Planet Aquariums, built the steel stand. A local wood worker build the stand skins and the canopy

  • Daniel says:

    I was waiting for this for a while I been a fan of yours for long time

  • Mark H. says:

    Mark, what editing software do you use?

  • Simon Ksiazek says:

    Hello Mark,

    Your reef tank has come a long way indeed! Also, I can’t believe how fast your kids are growing up. I remember seeing Bridger as a baby when u still had your 90 gallon tank! I am happy to announce that my wife and I are expecting a little baby girl right away! Had to take down my 34 gallon nano to make room in the baby room. I can’t wait to move into our “forever” home as well so I can introduce my child to the saltwater hobby! Our town-home will have to do for a few more years yet. As always, Keep em coming Mark.

    PS. I believe the ocean’s motions mechanism was invented in Canada, That’s why its dependable! Ha!

    Catch ya later!

    I was a little disappointed lol. i waited 2 months for a 6 minute video! i want more!

  • Matt says:

    Hey Mark,
    How do you like the ecoxotic lighting so far? Pros and cons?

    Also what is your take on kessil leds?


  • Chris Thomas says:

    What are the brand name of the hinges on your canopy. I’ve been looking for some for my canopy. Thanks.

    Hey Mark great update. Really looking forward to seeing your tank in a years time when it has started to mature.

    I was wondering what type of fish are the ones with the horizontal stripes of which you have several. They almost look like a type of butterflyfish.


  • Matt says:

    How do you run an oceans motions without a closed loop? Assuming you use it from the return, wouldn’t you be blasting water through your sump?

  • Dee says:

    The kids are growing up so fast. Super cute your little guy already filming. I guess you’ll have a kids corner soon. Tank looks good. Are you matching Par values or color levels from each light ?

  • Simon Ksiazek says:

    To Hawaiifavo:
    I think the fish you are referring to are called Australian Stripey! I saw them and was in awe as well.

  • paul says:

    Lovely tank
    cute munchkins as well, If you ever misplace one of your kids, check under the tank, looks like a great cubby house for a two year old and little sis!

  • Dagmar says:

    I secound the emotion on the ocean motion closed loop question.Beautiful tank and stand! Love the lighting experiment. Thank you!

  • Hawaiifavo…Simon has it right. They are Australian Stripies.

  • John says:

    What software do you use for the video? I want to run a similar format but for ice hockey. Thanks

  • John….I edit on Final Cut Pro X or Adobe Premiere Pro

  • Dee…I’m matching PAR values and matching color levels as best I can. The cannons have no color temp settings. Instead you have to ramp up/down the white/blues to get the color look you want. Same with the T5’s…a combination of bulbs have to be picked to get the temp you are looking for

  • Matt…I don’t rely on the ocean’s motions to provide lots of flow. I use it to mix up the flow and to create flow collisions

  • Chris…the hinges are blum hinges

  • steve from England says:

    Hi Mark , love the new tank and impressed with the lights.
    could you do us all in the U.K. a big favour, anytime you are talking to any lighting manufacturers , can you encorage them to sell direct to the U.K.
    Our lighting choice over here is pathetic compared to what you have in the U.S.
    M of your firms will not sell to the U.K. or will only sell here through agents which more than doubles the price of what you pay there , I know we would have to pay shipping charges but it would still be cheaper than buying from a agent here.
    I sometimes think it would be cheaper to jump on a plane and come over to the states with a big suitcase and buy a load of eqipment to bring back.
    Think we are still in the third world as far as aquarium technology is conserned

  • Scott says:

    Hello John,

    Regarding Adobe Premier Pro… It is a very good choice in software that allows linear and non-linear editing utilizing many video and audio tracks, 5.1 surround sound, and even green screen if you are in to that sort of thing. After Effects allows for adding special effects (such as lightning strikes). For me, it is pretty intuitive and easy to use, but it differs from person to person. It is pricey but you can’t go wrong with Adobe photo/video products. Have fun!!

    Hello Mark,
    WOW!!!!!!!!! Thank you very much for the update!!

  • Vasco says:

    Hi Mark! Congrats on the tank and most of all on the little ones! Your daughter is about the same age as my own so happy times! When can we have a video on the inhabitants? Or perhaps a little series of videos dedicated to each species, why you got them, reef safe or not, introduction order, care requirements, interaction, etc?

    Keep them coming!

  • Mark Hill says:

    Mark, glad to see your trying out the cannons! I’ve had two pairs on my 120 mixed reef for two years and love them. Hooked up with the apex controller and start up at 10% with a peak intensity of 30% ending at 10%. I’ve had excellent growth on all corals sps, lps, clams, and polyps. So much that I am fragging every 6 months and trading for supplies at my lfs. Crazy how fast kids grow too! I remember when my 15 year old daughter was in my arms. Miss those days. Great show As always! Thank you for sharing.

  • paul says:

    Stripies are a common species around the east coast of Australia, they steal bait in all our estuaries and bays, are they reef safe?

  • Matt says:

    Hey Mark,
    I noticed there is a circular hole on the overflow under one of the powerheads. What is that for?

  • Matt…the hole is for the wave box.

  • Paul…interesting that you say they are common as I was told they are hard to get here in the US. I’ve been waiting months to get some for clients. These fish are 100% reef safe.

  • Kyle says:

    Hey mark,
    I loved the video and all of you videos but really want to see a livestock video! I see some really pretty fish the blue throat trigger is awesome it’s a nice “fish on the fringe” haha! I know you might want to wait untill there are some corals but I can’t wait and I don’t think anyone else wants to wait! Can’t wait!

  • Kyle…I’m working on a livestock video.

  • Love the new tank. Thanks for the update, can’t wait to see how the light experiment goes. You have inspired me to create a youtube channel
