    Getting into your pyramid now since 2 years via the MARSH Moody Gardens "Backdoor tour" gave me quite some good picture about the operations and challenges you guys face over there ;-)

    I like to contribute some Livestock as well, even if I'm a bit handicapped at the minute due to the effects of Harvey, basically a flooded house. Anyways, I have worked night and day in the flooded house to keep my mini farm alive and everything is temporarily swapped over into a fully loaded 300G tank now and after a few days Nitrates went down to 1-2ppm means the thing is full cycled and ready to do some grow out jobs :-)

    I like to understand how you guys plan to replace water and elements in that Reef Exhibit which will help me and many others to choose the corals since most people have likely more sensitive corals to give away which makes your job later more difficult to keep it all alive.

    I was thinking to grow out a Nasuta and a specific Tenuis, lol
    Others may know what that means, lol.

    Let me know.

    Hey Andre,

    Hope everything is still going alright for you up North and things have begun to dry out.

    So the bulk of you question looks you're referring to where we get our source water for the exhibit and then how do we add additional elements to bring about balanced reef environment so I'll try and break it down into those two sections. First these are the current water parameters for the tank...

    Temp: 78.9
    Salinity: 1.0264
    pH: 8.16
    Ammonia: 0
    Nitrite: 0.009
    Nitrate: 2.8
    Phosphates: 0.2 - 0.5
    Calcium: 410
    Alkalinity: 8.96
    Magnesium: 1250

    I'm guessing that you are mixing your own salt water together using RODI water and a salt mix but you can imagine that becomes quite costly for someone with a 2,000 gallon tank, much less our 30,000 and 1 million gallons exhibits, but were fortunate enough to be located right next to Offatts Bayou in the bay. We pull raw seawater and store it in our treatment facility which over the next 48 hours goes through a chlorine treatment to kill any parasites, bacteria, algae and other pests followed up with an addition of proline to neutralize the chlorine leaving clean seawater. The water is then pumped through the entire aquarium and is used as needed. This is the water I use to perform my water changes every week and to clean out the quickly dirty portions of the exhibit.

    Seawater has been a great place to start but often times we're dealing with fluctuations of salinity/pH/temperature and other chemical aspects. We keep track of these through daily water quality checks we can make adjustments through chemical additions. Most, if not all, of the products we use come from Kent Marine as well as Fritz pro aquatics for our salt. All additions follow advised directions until the proper levels are reached. At the moment while the exhibit is pretty low on stock I have been using Turbo calcium as my calcium supplement but will be installing a full calcium reactor in the next week or two. The exhibit also possesses a GFO phosphate reactor to assists with phosphate levels. At this point in time we aren't too worried about the higher level of phosphates in the exhibit is they are helping provide a food source to help the exhibit mature and produce some algae for smaller reef inverts and such.

    Hope this was able to help, if you have any follow-up questions feel free to ask.

    Cheers,
    Ryan

    Very interesting and informative Ryan.
    Thx a lot.

    Where do you think is the P04 coming from?
    I remember having MARSHIANS going down to the beach and they tested really low Phosphorus levels.

    From my experience Po4 that high can be ok as long nitrates are not too low.
    So I would expect Nitrates to be in 4-8ppm range to avoid typical aquarium issues which your exhibit may not see in that size, means maintaining a proper redfield ratio.

    What lights do you guys have installed over the exhibit. I'm not sure if I did see the Reef exhibit from the backside.
    MH I strongly believe but what light color you will use? Just for my own curiosity ;-)

    Ohh let me be in on this challenge i would say lol! I'll see what corals I have To see them grow. But I'm going get my dad on board with this one too! Funny my teacher for aqua sci use to work at moody for like 7 years I think! We are going there next semester for a tour! But I'll think through out the day what coral I have that would be good!

    Thanks for the information Andre, it's interesting to hear that PO4 levels in the bay are low compared to what we are seeing here in the aquarium. To be honest I'm not entirely sure where the PO4 is coming from as we originally assumed it was from the bay. Where did you get your samples? Often times there are spills into the bay of excess nutrients from sewage that we sometimes hear about that reach into Offatts Bayou (if you go diving out there you can see a sulfur line from the building yards on Pelican Island next to A&M). It's a theory but something worth us looking into. Fortunately nitrates are climbing slowly so I'm not terribly worried about issues, when the time comes I will also incorporate SeaKlear which is a PO4 binder that can be used to extract even more.

    For lighting we've swapped from MH to LED's. We are now using the MaxSpect R420R on all of our exhibits, including the reef. It's one that's been suggested to us by other aquarists within the industry who have had exceptional results. We're continuing to see improvements as the lights become more dialed in to what the corals need and are now focused on the ones that are still recovering from the original stress. We do have a stash of MH nearby in case we decide that it's best to switch back in the future.

    Cheers,
    Ryan
