    Replacement LED diodes for AI Prime 16

    in Equipment

    Posted

    My guess the two that burn out are SemiLED 415nm & 400nm

    It will be hard to find replacement since there are several version of these diodes and I am sure AI won't give out that information.

    Both are in the same channel and run on a different MA than the rest.

    I am not sure if the replacement module still available from AI, you have to replace the whole mother board if going to AI

    This company may have the supply that you need and they should be able to fix it for reasonable price, https://www.fixreef.com/mail-in-repair/

    RODI thoughts and question

    Ok I can see how thats a lot better in the long run. 44 gallons in 10 minutes!! That's awesome, How often are you replacing DI resins? 

    Thanks for the info, I'm gonna keep it how it is, since I'm not trying to make tons of water.  

    I have 2X 1 cu ft media / 50"x9" media cylinder. Last me 2 years before it gets to 1-2tds.

    In general di filter capacity in pppm divide by tds will give you approximate gallon capacity. A good quality 5lbs di media has a capacity of about 14000ppm

    A good prefilter before DI will make di last longer. Prefilter being carbon/catalytic carbon/sediment/ro

    RODI thoughts and question

    in General Discussion

    Posted

    RO and DI filters work with minimum flow/pressure rating (gpm), the filter unit always stated as how much it produce as gpd.

    We thought that reducing the flow / pressure would make the water spend more time in the filter and will filter better. It is actually the reverse happened, less filtration or improper filtration flow when minimum flow or pressure not follow. In the case of DI, IME resin will be exhausted faster with less quality (higher tds) water when minimum flow requirement is not flowing through the chambers.

    Ready RODI unit has been set to proper minimum flow/pressure rating usually stated in the manual, sometimes if minimum pressure / flow is not met a booster pump is needed so the unit can have proper range of flow/pressure.

    The only reason I go with no waste water is the cost of water. I used to have close to 12K gallons of saltwater systems, having waste water to feed this systems for new water mix will cost a lot in the water bill alone. Now I only have about 1000 gallons systems and go through 200gal a week. Certainly the cost with waste water is not much now but I like to fill 44gal brute container in about 10 minutes so I still go with no RO just for my convenience.

    RODI is the best water quality you will ever get for reef tank, this should be the top priority on any filter you choose.

    Branching Zoa's???

    Looks like zoa growing on coral piece. They come like this all the time on maricultured pieces.  Zoas don’t come in a hard skeleton.  @goldenbasketreef I remember seeing your zoa pieces coming this way .

    My guess it is a type of colorful stick polyp / Ancrozoanthus spp. It does form a soft branch as the colony become longer

    I have brown / black all the time never the color as per picture above.

    CITES and the implications for the hobby

    If this is up to date I think it should be CITES 2? 

    Yes, Rhizotrochus spp is in appendix II CITES, which means OK to trade. However, one reason that I mentioned above is that interpretation to each CITES country member would dictate allowing the trade or not. In the case of the US, it is not allowed to be imported or traded because there is no scientific data to estimate the wild population number.

    Being in appending II CITES is only the first step. Each exporting CITES member country must establish an export quota based on scientific study. An export quota is a total number of this Rhizotrochus spp allowed for export in one calendar year.
    If we look at CITES database no coral exporting country has Rhizotrochus spp listed in their respective 2022 quota year. So since no export quota there is also no collection permit in the country origin and no export CITES has been issued for Rhizothrocus spp.
     
    How can it exist in the US?
    Through illegal import by falsifying import documents to declare Rhizotrochus spp as Tubastrea spp or Dendrophyllia spp. So many corals being imported just overwhelmed the job of USFWS inspection agents.
    Irresponsible importers taking advantage of the situation, this is why as a reefer we have to take a proactive approach to reject this type of product.
     
    An import shipment cleared customs and USFWS so the import shipment with Rhizotrochus spp is legal?
    Not really, Customs and USFWS import/export clearance is temporary in nature. The import shipment is cleared based on a given information at the time of import but can be revoked later up to 5 years later if new evidence is obtained to show the false documentation.
    US management authority position has always been if a coral is illegally collected or illegally exported, it can't never be legal by any means.
    The law required every importer to show an import declaration form if requested by a buyer when a question arises as to the legality of coral being imported. Also the seller must give a signed statement that the coral sold is imported legally if demanded by the buyer.
    For example if a Rhizotrochus spp is listed in CITES documentation the same as in USFWS declaration form then the import is legal.
     
    Rhizotrochus spp is one example of many other corals being imported by falsifying documents.
     
     The coral trade is a highly regulated trade that the law demands both commercial operators and individual hobbyists to be an aware and responsible party.
