Cedric you are welcomed! Love to visit your house to see all those zoas again! My zoas are doing really well in my tank! Thankls for helping out and sharing your experience taking care of the zoas!
My nitrate is near zero. Not sure is it bcos my test kit expire. There is no expire date on the test kit. So I think it has no expired bah on this brand of test kit. I intro naturally seawater initially then recently switch back to me salt.
