  • PO4 from CaRx what to do?

    Hey guys finally had some time tonight and ran a complete round of test. I also tested the PO4 coming from my CaRx (Deltec pf500 w/ deltec media). I did the test with the Hanna meter and guess what i got?

    .04!!!!!!

    so now what can i do about this? i remeber seeing something i think on Edward's tank that contained some type of media that the CaRx effluent went dirrectly into then ran down into the sump.

    do i need to get something made? if so who can make it for me? and what type of media can i use to remove the PO4 coming from the effluent of the CaRx?

    i think if i can even get it down to .01-.02 coming from the CaRx i think that would be better than .04 that i am getting now.

    i am about to refill my CaRx in a couple days with fresh media that i have been soakig in RODI water for a good week changing the water every day.

    so ideally if i need something made i want to get on it. i mean is it something i can DIY? or no?

    anyway thanks for any help anyone can give me.

      I could'nt get the pics to come up on the last post but absolutely biophose 3 for PO4 removal. I made one like Alexanders for probably like $5 out of Home Depot. Just used the plastic drain kits like you would get to replace plumbing under sink. Maybe Alexander has a pic in his gallery.

        I cant see the pics either.

        Edward if you are out there can you post som emore?

        i thought that the BipPhos 3 was what i was supposed to use just wanted to make sure.

        can you post a pic of yours please.

        did you test before and after making this?

        thanks

          Nick for those purposes any of the aluminum based PO4 removers will work.

            Thanks,

            how often do you need to change this stuff out?

            also how do you know when to change it and how much should i use at a time?

            thanks

                    Alexander- could you explain how that works? it seems pretty simple and something i might be able to make.

                    thanks

                      Nick, it is really simple. The return tube from the CaCO2 reactor (blue) is connected with the drain which can be filled with a PO4 absorber or some coral gravel. The water flows through drain and the material and back to the tank. The siphon holds back all the small particles coming from the reactor at its upper arc which provides crystal clear water in the tank. The drain has to be cleaned regularly, 4 weeks works fine.

                        That's a smart design, even a tool like me would have a shot at building that

                          Dear Alexander...
                          so you change po4 absorber every 4 weeks?

                            Vince, I have stopped the usage of a PO4 absorber in the drain, just running coral gravel to bring up the PH a little bit before the water goes back to the tank. I use a PO4 free coral gravel after soaking it in RO water several times before I fill it in the reactor so a absorber is not necessary. If one uses absorbers, the replacement interval really depends to the PO4 quantity which is leached by the used media, but this is easy to monitor with a regular PO4 measurement.
