I have 2 brand new unopened boxes 55g mix each, individually sealed bags for 4.5/5g mix depending on your salinity preference.
Accurasea1 by Julian Sprung. Each bag contains 4.5/5g premeassured mix. Individual bags are supposed to have the exact mix as the last bag with no separation of trace elements in the mix. Alk is @ 8.0 when mixes @ 1.025, CA 420 and mag 1360.
I have an addition half box as well. Used for a month before switching to tropic marine pro. Mixes clean with no residual residue, can add to tank as soon as it mixes clear, aprox 1 hour mixing.
50$ for all 2 1/2 boxes or trade for zoas, Yumas, leathers, gorgs
