    Hey peeps...
    I am asking your help with regards to something.

    I am setting up my tank, and wanting everything to be 100% before I go and start adding corals.

    I was curious, and find out that my PO4 with my ready mix water has a reading of 1ml per litre. Tested my RO water and that is fine.

    I am using Seachem's Reef salt.

    Any ideas? :whistling:

    Which test kit?
    Could be the salt, but I have seachem recently and no PO4
    New container you mixing in? Fill that with some RO and test, maybe it's leaching PO4

    Its sera. (Not the best as I know) But there is a significant difference. However, I did clean the container last week. Didnt use any commercial cleaning products, and dried it properly afterwards too. So Im scratching my head

    I would think its the container

    Make a liter with RO and test that, use glass container if you can, elimination is the name of the game

    would the heat from the salt cause a reaction to the plastic allowing for chemicals to be expelled out into the water?

    I have also noticed a white residue on the clear plastic container. Is this Ca build up, that cant be cleaned off by a pressure hose, or is it the heat melting the plastic?

    I don't think it's heat, but do the glass container test

    I have experienced the same with salinity, Red Sea Coral pro and Microbelift.
    Didn't have the PO4 issue though. Just the residue, didn't bother me.

    Like Dallas said, elimination is the way to go. Only change one factor at a te though.

    Good luck.

    Most likely the kit. The residue is CACO3 falling out of solution. As dallas said, test using a glass bottle.
