    I bought a Hanna HI96713 photometer.
    I'd gotten a couple of erratic results from the LFS I'd been taking water samples to (they have the Hanna HI93713 shown in the original post). I think the LFS employees would get distracted and either record the wrong information or read things incorrectly. I've also replaced all of my salifert kits with new ones. I've noticed the kits begin to lose accuracy after a year, so I replace them every year.


    I also sent Tristan this email:


    "Tristan,
    I dont recall if I mentioned this or not when we spoke, but my system had multiple issues some of which only got worse after I neglected the system for abit after my heater crapped out....shocking that things get worse when you neglect them, I know...


    So here is where the questions for you come in....

    Using new salifert test kits, and a new and newly calibrated Hanna HI96713 photometer, my parameters are:

    DKH - 11.5
    Ca - 460
    Mg -1500
    NO3 -0.00
    PO4 - 0.00

    Bryopsis appeared and has a foothold. I raised Mag up to take care of it, and have noticed the tips have frosted indicating it's working. I've done this in the past, (raised Mg up to 1700 and kept it there for 3 months to eradicate bryopsis with no ill effects to fish, clams, SPS, or anemones), but I didnt have the ARID E18 then either.

    I've been told elevated Mg inhibits photosynthesis in bryopsis, but doesnt affect other marine algea, to inlcude Cheatomorpha. Do you see elevated Mg causing an issue with the Cheatomorpha, or is this a non issue? I'm still seeing growth in the Cheato in the reactor and PO4 has dropped from 0.02 to 0.00, but I'd still feel better bouncing it off of you.

    NO3 is showing as 0.00 but I still have green cyano in the system, so I know there is NO3 available, and it's being taken in by the cyano. Will the Cheato out compete it for NO3? I'm leery of dosing NO3 when I have cyano in the system for fear of feeding it instead of the Cheato. Do you recommend:

    Let the Cheato outcompete the cyano and dose the NO3 supplements as instructed.

    or

    Use Chemi-Clean and take care of the cyano, then begin dosing the NO3 supplements.


    Overall, I'm very happy with the reactor. PO4 is still much better than before and corals are looking better already. The threads on Reef Central and on Manhattan Reefs are the biggest and most active so far, and there are alot of people who seem genuinely interested in your ARID reactors. Locally, I've brought this up to the LFS where I usually go, and directly sent a link to the RC thread for the manager and owner....with any luck, they may become customers or a dealer for you as this store does alot of maintenance and set up work for businesses and individuals with aquariums.

    Finally, over on Manhattan Reefs, one poster stated Joe Yaiullo was in the process of setting up eight ARID C30's for the Atlantis Marine World 20K gallon tank...is this true? I'm hoping it is because that would give you guys more exposure and "legitimacy" in the eyes of folks who havent yet heard of you guys and the ARID reactor. People say all kinds of things on the Net and I'd prefer to have confirmation before parroting that information about elsewhere.

    I apologize for pestering you with these questions, but this is a new situation for me and I'm loathe to do anything that will be counter productive to what progress I've already made.

    Thanks for your time,

    MaxxII"

    Here is his response:

    "Hi Nick,

    Stop resisting the Nitrate supplement

    The cyano doesn't require nitrate in the water column to grow, it produces it's own nitrate and thrives when nitrate is not present in the water column. This is cyano bacteria's evolutionary advantage, being able to fix nitrogen into nitrate it can survive where other photosynthetic organisms can't. Dose the nitrate keep the ratio between 20:1 - 200:1 (target 100:1)

    Same with the bryopsis. This is turf algae that uses its holdfast to extract nutrients from the rock (substrate) Elevated Mg does kill off Bryopsis, at 1500ppm your Chaeto should be fine. I've only noticed it stunting the growth around and beyond 1600ppm.

    Your other parameters look great. One other kit I recommend is saliferts boron test kit. Macro algae consumes a lot of boron and most salt mixes are deficient. Luckily there is a cheap source at your local grocery store "Borax" laundry booster. 1 teaspoon raises 100 gallons about 1ppm. NSW is 4.4ppm. Brittle and crumbling chaeto is a sign that your tank is boron deficient. Toxicity in a small number of organisms starts to occur around 20ppm.

    Yes, Joe Yaiullo bought the C308 system that is in our MR forum. He is setting it up on his 20k gallon reef as soon as he builds a platform above the reef for it. I may go out there and help him set it up. He's my old boss, I use to culture coral for that tank.

    Glad the E18 is working out for you. Now you'll have to feed your tank more.

    Regards,

    Tristan"

    I've bedn dosing the NO3 supplements for a few days now.

    I have about 135/140 gallons total in the system right now.

    Started dosing 2mls of the included NO3 supplement.
    No change in NO3 readings, still undetectable via salifert.
    Next day dosed 4mls.
    No change in NO3 readings, still undetectable.
    Last night I dosed 8mls of NO3.
    14.5 hours later I tested and finally got some detectable results.

    NO3 showed less than 0.2...it appeared to be about half as much so I ballparked it at about 0.1.
    At this point, I goofed. I'm still working midnights and had not had coffee yet, so my brain wasnt fully engaged.

    I should have tested for PO4 at this point.
    Instead, I dosed an additional 8mls of NO3, and added Nori to the tank,(which I know from experiance does have PO4 in it).
    Then it dawned on me that I should have tested PO4...

    I went ahead and tested PO4. Elapsed time between dosing NO3 and adding Nori to the tank and fosing NO3 was approximately 5 minutes.

    PO4 measured at 0.00978 ppm.
    So basically at 0.01 ppm. With NO3 being at 0.1 ppm and PO4 being at 0.01 ppm, I'm at the 100:1 ratio that Tristan reccomends for the ARID reactor.

    My ARID Reactor has been running for almost a month now, and I'm still happy with it and its doing exactly what it's supposed to do.

    I've also got some additional KNO3 powder coming so I can start making my own NO3 supplement. Using 8mls a day means I have about 13 days left in the included bottle of supplements.

    As always, further updates as warranted.
