Mr. Saltwater Tank

Some of This, a Little of That and NONE of Something Else (An update on Mr. Saltwater Tank’s 235g Tank)

I’m not coming out of the closet, but my tank is!

In this episode of Mr. Saltwater Tank TV, I update you on my 235 gallon tank including my marine velvet survivors. I’ll show you what’s changed, what I’ve left alone and who I want to give a shout out to.

    Love your tank!

    Sorry my phone types what it wants sometimes

  • James…placement of the Matrix doesn’t matter.

    If you want to do a refugium, make sure you watch this show.

  • Gene Savage says:

    Hi Mark,

    what type substrate are you using?

  • Gene…Tropic Eden Reef Flakes

    I live in Nashville; could we get together and talk about tanks?

  • Tom S. says:

    Mark, how did you “dry” your live real reef rock? Just bleach it in the sun?

  • Rob Melo says:

    Hey Mark great show can’t wait for more. Glad to see that your tank is back online and
    Looking good. I noticed you dumped the swc skimmer for a hydor recirc. What made you decide on the hydor rather than another swc.

    Thanks again for all that you do,

    Hi Mark,
    Is there a reason behind why you will not be creating a refugium on this setup? Can you elaborate a little more on your reasoning for that. Is it simply because you didn’t have the space or did you notice it was really more of a hassle to maintain? I’m starting a new tank and I was wondering if I should go the refugium route or skip it.


  • Danaysis…a refugium won’t do much for nutrient control until they are of good size compared to your tank volume. Given my tank size of 235 gallons, I’d want at least a 100 gallon refugium which isn’t possible given my space constraints.

  • Rob…I didn’t have space for another SWC and I wanted to try out a recirculating skimmer. I never had any complaints with my old SWC and still recommend that brand for peole.

  • Tom…I left it out in the sun for a couple of days.

  • Mike says:

    Mark are you running the marine or pond version of matrix? I want to use this in my sump but I want to make sure that it will not fall through the egg crate shelf.

  • Mike…the pond version.

  • Ryan S says:

    Mark, are you able to sell the TIR lenses yet? If so, can you email their price shipped to 22204? (I have 2 radions) Thanks.

  • Gary says:

    Wonderful to see your tank up and running again! You mentioned you are a zoa guy at heart, think you will ever do a video about just them? I just took the first step into the coral world with a small zoa colony.
    Thanks again for all the awesome videos!

  • Gary…hmmm…just a zoa video. I can see 50% of it being just eye candy shots!

  • Bryan says:

    Hello from Austin, Texas Mark!

    I’m curious about your update on the matrix idea. I’m wanting to pull the trigger on something soon.

    Take care,

  • Nick says:

    did you ever do the review of your new sump?

  • Lisa says:

    How do you spell the name of that white coral you mentioned? I like it.

  • scruffbud says:

    Hey Mark
    If I may ask, how was the Matrix working out in your old tank and are you using it in your new one??

    Hope all is well..
